Title: Dry adhesive with a selective adhesitivity

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from U.S. Provisional Patent Application Ser. No. 61/446,633, filed Feb. 25, 2011 and entitled “DRY ADHESIVE,” which is hereby incorporated herein by reference in its entirety for all purposes. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to adhesives. More specifically, the present invention relates to surface specific adhesives. 
     BACKGROUND OF THE INVENTION 
     Typical adhesives generally are liquid or semi-liquid that bond similar or dissimilar materials together by curing through evaporation of solvents and/or chemical reaction of one or more constituents. While liquid or semi-liquid adhesives are useful in many joining applications, a disadvantage of liquid or semi-liquid adhesives is that it takes a long time to cure the adhesives, i.e., the joining step is not immediate. Furthermore, liquid or semi-liquid adhesives often give off volatile organic compounds (VOC) that are toxic, have limited pot life, and/or have limited shelf life. Liquid adhesives are difficult to apply in a uniform manner, often showing shrinkage. From a process and application viewpoint, heat and pressure, jigs and fixtures for the joint geometry, rigid process control, inspections, and training are often required. Other issues include variable viscosity, evaporation, and/or substrate contamination. 
     Various typical dry adhesives have been developed to overcome the disadvantages of liquid adhesives. For example, pressure sensitive adhesive (PSA) single-coated tape products are examples of dry adhesive products consisting of a backing material, primer, adhesive, and release agent or liner. In general, pressure sensitive adhesive products require the adhesive to be tacky and easily deformable, i.e., soft, for adhesion to another surface, i.e. adherend. There are other adhesion considerations such as PSA chemistry, surface tension, and surface preparation that are considered to appropriately matching of PSA to various substances. The negative issues associated with PSAs include dwell time to gain full adhesive strength while under pressure, mismatch of surfaces, surface preparation time, lower adhesive strength, and limited shelf and working life. 
     Other typical dry adhesive products are hot melt adhesive products. Hot melt adhesive products are typically thermoplastic copolymers tackified with resins. Hot melt adhesive products have limited use because high temperature is required to melt the adhesive to join the desired surfaces. The hot melt adhesive is typically heated above its melting point to a molten state and rapidly solidifies to form the bond between the desired surfaces. There are many disadvantages to hot melt adhesives including potential injury to persons applying the adhesive, time to heat the adhesive, heat damage to the substrate, and limited range of properties. 
     Although Velcro® is a mechanical fastener using hook-and-loop and is not an adhesive, Velcro® is employed as a dry fastener to join together similar and/or dissimilar surfaces. Velcro® typically consists of two layers. A first layer consists of a first backing covered with tiny hooks, and a second layer consists of a second backing covered with tiny loops. When the hook side is pressed together with the loop side, the loops catch the hooks and hold the first backing together with the second backing. However, Velcro® is able to accumulate hair, dust, and fiber in the hooks and reduce the efficiency of the fastener. Further, Velcro&#39;s® hooks are able to easily grab onto woven items such as a sweater and are able to cause damage to the item upon removal. 
     SUMMARY OF THE INVENTION 
     A selective adhesive mechanism is able to comprise an engineered surface and a compliant member. The compliant member is able to be dry and a non-tacky substance. The compliant member is able to be selectively adhered to the engineered surface when the compliant member is in contact with the engineered surface. 
     In a first aspect, an adhesive mechanism comprises a first member having an engineered surface and a second member comprising a compliant member to be selectively adhered to the engineered surface selectively. The compliant member is able to form an adhesive bond with the engineered surface when the compliant member and the engineered surface are brought into physical contact. The compliant member is able to comprise a polymeric member. The polymeric member is able to comprise a silicone polymer and a silicon based polymer. The silicone polymer is able to comprise a silicone gel or silicone rubber. The polymeric member is able to comprise a thermoplastic elastomer. The polymeric material is able to comprise a dry, non-tacky, or a combination thereof substance before coming in contact with the engineered surface. The selective adhesive is able to result from mechanical interlocking between the engineered surface and the polymeric material. Further, the selective adhesive is able to be complemented by intermolecular forces. The intermolecular forces are able to comprise a hydrogen bond, van der Waals force, other adhesive forces, or a combination thereof. 
     In a second aspect, a method of forming an adhesive mechanism comprises preparing a first dry material and a second material and detaching the first dry material from the second material, wherein the first dry material is capable of being instantly removable from the second material without substantial damage to the first dry material. The adhesive property of the first dry material is able to be surface selective, such that the first dry material is able to be adhesive to the second material selectively. The first dry material is able to comprise silicone. The method is able to further comprise applying the first material to a device, such that the first dry material forms an immediate attachable and detachable, repositionable mechanism on the device. The term “immediate” used herein is able to include the meaning of instant, close in time, and proximate, such as less than two seconds. 
     In a third aspect, a set of adhesive material comprises a first surface containing a silicone rubber and a second surface containing a chemical substance that is selectively adhered to the silicone rubber. The silicone rubber is able to be molded to attach with a device or enclose the device. The device is able to comprise one or more hand tool, electronic device, equipment, office supply, kitchen ware, decoration, or a combination thereof. A person of ordinary skill in the art will appreciate that any devices are applicable so long as it is physically tangible. The second surface is able to comprise one or more wall, paper, medical device, electronic device, or a combination thereof. 
     In a fourth aspect, a method of using an adhesive material comprises coupling a device containing a compliant member to an engineered surface by forming an area of selective adhesion force between the compliant member and the engineered surface when the compliant member physically in contact with the engineered surface and decoupling the device from the engineered surface by gradually reducing the adhesion force between the compliant member and the engineered surface. The compliant member is able to comprise silicone polymer or polyurethane. 
     In a fifth aspect, a polymer containing member comprises a polymeric material having selective adhesion to a surface when the hardness of the polymeric material is within a preselected range of Shore A scale of a durometer. The range is able to be lower than 42 Shore A hardness, such as between 42 and 0, when the polymeric material comprises silicone rubber. The range is able to be lower than 55 Shore A hardness, such as between 55 and 0, when the polymeric material comprises polyurethane. 
     In a sixth aspect, a coated member comprises pores capable of forming selective bonding with a polymeric substance. The pores are able to have sizes capable of fitting a portion of the polymeric substance, so that the selective bonding is formed. The bonding is able to be formed when the polymeric substance is within a pre-selected hardness. The range is able to be lower than 42 Shore A hardness when the polymeric material comprises silicone rubber. The range is able to be lower than 55 Shore A hardness when the polymeric material comprises polyurethane. 
     In a seventh aspect, a fastening device comprises a first surface containing a polymeric material and a second surface containing an engineered surface, wherein the fastening device is able to fasten an object when the first surface is in physical contact with the second surface. The fastening device is able to comprise a twist tie.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention will now be described in detail with reference to a few embodiments thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention is able to be practiced without some or all of these specific details. In other instances, well known process steps and/or structures have not been described in detail in order to not unnecessarily obscure the present invention. 
     Various embodiments are described herein below, including compositions, methods, articles of manufacturing, and techniques. Further, the invention is able to also cover apparatuses for practicing embodiments of the present invention. 
     The features and advantages of the invention are able to be better understood with reference to the figures and discussions that follow. 
       FIG. 1  shows a simplified schematic of a particulate coating in accordance with one or more embodiments of the present invention. As shown in the example of  FIG. 1 , first surface  102  is able to be coated with particulate coating  104  to form an engineered surface  106 . In some embodiments, the first surface  102  comprises a porous surface. Non-limiting examples of the porous surfaces comprise paper, corrugated box, masonry, drywall, wood, ceramics, woven and non-woven (many examples including diapers) substrates. In other embodiments, the first surface  102  comprises a non-porous surface. Non-limiting examples of the non-porous surfaces comprise plastic, rubber, metal, and glass. 
     In some embodiments, the particulate coating  104  is able to be configured to adhere on the first surface  102 . The particulate coating  104  is able to be applied to the first surface  102  as a liquid coating. The liquid coating is able to comprise submicron particles of fumed silica and/or fumed alumina. The size of the aggregate submicron particles is able to be in the range of about 0.2 to 0.3 microns. The submicron particles are able to have surface area in the range of about 50 to 400 m 2 /g. A person of ordinary skill in the art would appreciate that the liquid coating is able to contain particles in any sizes (such as micrometer, nanometer, and picometer) and having any corresponding surface area. 
     Examples of the aforementioned fumed silica or fumed alumina are able to be CAB-O-SPERSE®, CAB-O-SIL®, and SpectrAl™ manufactured by Cabot™. 
     The particle(s) or a mixture thereof are able to be present in a liquid coating composition in the range of half of a percent (0.5%) to about fifty percent (50%) by weight, more preferably in the range of about one percent (1.0%) to about forty percent (40%) by weight, and even more preferably in the range of about two percent (2.0%) to about thirty percent (30%) by weight. A person of ordinary skill in the art would appreciate that any weight percentage of the particles in the liquid is applicable. For example, the effective concentration of the particle(s) is able to depend on the percentage by weight of the particle(s) required in the liquid coating composition to produce the desired surface properties. 
     The liquid coating is able to comprise at least a binder. The binder is able to be a polymer employed to keep the particles adhered to each other and to the first surface  102 . In some examples, the liquid coating comprises one polymer if the polymer is able to effectively act as a binder to keep the particles adhering to each other and to the first substrate  102 . In another example, the liquid coating comprises two polymers, wherein a first polymer is able to be employed to keep the particles adhered to each other while a second polymer is able to be employed to adhere the particles to the first surface  102 . In yet another example, the liquid coating comprises a plurality of polymers, wherein a first polymer is able to be employed to keep the particles adhered to each other, a second polymer is able to be employed to adhere the particles to the first surface  102 , and a third polymer is able to be employed to adjust the viscosity of the coating. Thus, the liquid coating is able to comprise at least one polymer to achieve the desired end properties of the coating. However, a plurality of polymers is able to be employed to achieve the desired end properties of the coating. 
     Examples of suitable water-soluble and water-dispersible polymers are able to be included in the liquid coating compositions of the present invention include, but are not limited to, acrylic, polyvinyl alcohols, polyvinyl pyrrollidone, polyester emulsion, styrene maleic anhydride, cellulose acetate resins, and derivatives thereof. Analogously, suitable solvent-soluble resins with water tolerance are able to include, but are not limited to, acrylic, cellulose acetate, polyketone, polyvinyl alcohol, phenolic, novolac resins, and derivatives thereof. 
     Examples of the aforementioned resins or polymers are able to be Joncryl® manufactured by S.C. Johnson, PVP manufactured by Air Products™, MOWIOL® manufactured by Kurary™, and Synthetic Resin DS manufactured by Degussa™. 
     The polymer(s) or a mixture thereof is able to be present in a liquid coating composition in the range of half of a percent (0.5%) to about thirty percent (30%) by weight, more preferably in the range of about one percent (1.0%) to about two percent (20%) by weight, and even more preferably in the range of about five percent (5.0%) to about fifteen percent (15%) by weight. A person of ordinary skill in the art would appreciate that any weight percentage of the polymer(s) or a mixture thereof in the liquid is applicable. For example, the effective concentration of the polymer(s) is able to depend on the percentage by weight of the polymer(s) required in the liquid coating composition to produce the desired binder and/or viscous properties. 
     The liquid coating is able to comprise surfactants. In some embodiments, the surfactants are employed to modify the surface tension of the liquid coating to improve wetting of the coating on the first surface  102 . Surfactants suitable for use in the various coating compositions of the present invention are able to comprise ionic, zwitterionic (amphoteric), and/or non-ionic surfactants. Surfactants are surface active agents that contain both hydrophobic groups and hydrophilic groups. Surfactants are generally able to be characterized by the presence of a charge on the hydrophilic group of the molecule. For example, non-ionic surfactants are able to have no charge on the hydrophilic portion of the molecule; whereas, ionic surfactants are able to have a net charge on the hydrophilic portion of the molecule. Negatively charged surfactants are called anionic surfactants, whereas, positively charged surfactants are called cationic surfactants. Furthermore, surfactants with two oppositely charged groups on the hydrophilic portion of the molecule are called zwitterionic surfactants. More generally, surfactants are able to be hydrocarbon-based surfactants, silicone-based surfactants, or fluorosurfactants. 
     Examples of the suitable hydrocarbon-based surfactants are able to include, but are not limited to, acetylenic-based surfactants. For example, acetylenic surfactants that are available from Air Products™ suitable for use in coating compositions such as Dynol™ 604, Dynol™ 607, Surfynol® 104, Surfynol® 104A, Surfynol® 104BC, Surfynol® 104DPM, Surfynol® 104E, Surfynol® 104H, Surfynol® 104NP, Surfynol® 104PA, Surfynol® 104PG50, Surfynol® 104S, Surfynol® 2502, Surfynol® 420, Surfynol® 440, Surfynol® 465, Surfynol® 485, Surfynol® 485W, Surfynol® 502, Surfynol® 61, Surfynol® SE, Surfynol® SE-F, and Surfynol® TG-E.

     The surfactant(s) or a mixture thereof that are contained in a coating composition is able to be in the range of five hundredths of one percent (0.05%) to about three percent (3%) by weight, more preferably in the range of about seventy-five thousandths of one percent (0.075%) to about two percent (2%) by weight, and even more preferably in the range of about one tenth of one percent (0.1%) to about one-and-a-half percent (1.5%) by weight. A person of ordinary skill in the art would appreciate that any percentage of the surfactant(s) or a mixture thereof in the coating composition is applicable. The effective concentration of the surfactant(s) is able to depend on the percentage by weight of the surfactant required in the liquid coating composition to produce the desired surface tension and wetting properties. 
     In accordance with some embodiments of the present invention, alcohols are able to be employed as the fast-drying solvent in various coating compositions to modify the drying property of the resulting coating material. Alcohols suitable for the coating compositions in accordance with some embodiments of the present invention include, but are not limited to, methanol, ethanol, isopropyl alcohol, n-propyl alcohol, tert-butanol, n-pentanol, benzyl alcohol, and derivatives thereof. 
     In some embodiments, methanol is added to the coating composition to increase the drying rate. In some embodiments, benzyl alcohol is added to slow down the drying rate of a coating composition. An effective concentration of alcohol is able to be empirically determined based on the applications, so that desired drying rates to specific applications are able to be attained. 
     In some embodiments, an alcohol and/or a mixture of alcohols are able to be in the range of about one percent (1%) to about seventy-five percent (75%) by weight, more preferably in the range of about five percent (5%) to about fifty percent (50%) by weight, and even more preferably in the range of about eight percent (8%) to about forty percent (40%) by weight. In some embodiments, the alcohol is able to be added individually and/or as a mixture of different alcohols in an effective concentration to achieve desired properties. A person of ordinary skill in the art would appreciate that the term “desired property” described herein comprises desired properties at any stage of the manufacturing process, such as before, during, and post manufacturing process. 
     In some other embodiments, glycol ethers and/or esters are able to be employed as the fast-drying solvent in various coating compositions to modify the drying property of the resulting coating. 
     The suitable glycol ethers employed in various coating compositions in accordance with some embodiments of the present invention include, but are not limited to, propylene glycol methyl ether (“glycol ether PM” or “GEPM”), dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol normal propyl ether, dipropylene glycol normal propyl ether, dipropylene glycol normal butyl ether, dipropylene glycol normal butyl ether, tripropylene glycol normal butyl ether, dipropylene glycol tertiary butyl ether, diethylene glycol methyl ether, diethylene glycol ethyl ether, diethylene glycol butyl ether, and derivatives thereof. 
     In some embodiments, the esters suitable to be employed in the coating compositions include, but are not limited to, amyl acetate, iso-butyl acetate, n-butyl acetate, glycol ether DB acetate, glycol ether EB acetate, glycol ether DE acetate, glycol ether EE acetate, glycol ether EM acetate, glycol ether PM acetate, ethyl acetate, ethyl-3-ethoxy propinate, isopropyl acetate, n-propyl acetate, isobutyl isobutyrate, dibasic ester, and derivatives thereof. 
     In some embodiments, the glycol ethers and esters are able to be employed as co-solvents to balance various properties of a particular coating composition. In some embodiments, a relatively fast-evaporating solvent such as ethyl acetate is able to be employed to increase the drying rate of a coating composition. In some embodiments, alternatively or concurrently, a relatively slow-evaporating solvent such as glycol ether PM acetate is able to be employed to decrease the drying rate of a coating composition. In some embodiments, glycol ethers and esters are added to a coating composition in various combinations and effective percentages by weight to achieve the desired balance in properties. 
     In some embodiments, oxygenated solvents suitable to be employed in the coating compositions include, but are not limited to, glycol ethers such as propylene glycol n-propyl ether (“Glycol Ether PnP”), tripropylene glycol methyl ether (“Glycol Ether TPM”) and/or dipropylene glycol methyl ether (“Glycol Ether DPM”). 
     In some other embodiments, Glycol Ether PnP, Glycol Ether TPM and Glycol Ether DPM are employed in the coating compositions to offer co-solvency with a wide range of solvents and functional groups. In particular, Glycol Ether PnP, Glycol Ether TPM and Glycol Ether DPM are hydrophilic as well as having a low enthalpy of evaporation. The hydrophilic nature of the Glycol Ether PnP, Glycol Ether TPM and Glycol Ether DPM are able to provide good co-solvency with water and other solvents employed in coating compositions according to some aspects of the present invention. Further, the hydrophilic property of Glycol Ether PnP, Glycol Ether TPM and Glycol Ether DPM are able to help retard water evaporation in the bulk coating composition according to some aspects of the present invention. However, when the coating composition is atomized through the nozzles onto a substrate, the low enthalpy of evaporation property of Glycol Ether PnP, Glycol Ether TPM and Glycol Ether DPM are able to allow faster evaporation and enhance faster dying of the coating on the non-porous substrate. 
     In some embodiments, various mixtures of the aforementioned fast-drying solvents are able to be selected at an effective concentration in terms of percentage by weight for particular coating formulation, thereby providing desired properties. 
     In some embodiments, appropriate solvents are selected for a fast-drying coating to adhere on a wide range of non-porous substrates. The solvents are able to include one or more of the following features: substantial solubility with water; desirable evaporating rate; substantial miscibility with water; relatively low toxicity; relatively low viscosity; substantially complete dissolution of water-insoluble dyes; and substantially complete dissolution of resin. 
     In some embodiments, a fast-drying solvent and/or mixtures thereof are present in the range of about five percent (5%) to about ninety percent (90%) by weight, more preferably in the range of about ten percent (10%) to about seventy-five percent (75%) by weight, and even more preferably in the range of about ten percent (10%) to about sixty percent (60%) by weight. A person of ordinary skill in the art would appreciate that any percentages are applicable. 
     In some embodiments, coating compositions comprise a colorant which is able to be a dye, a pigment, or a combination thereof. Any colorants that are able to be dissolved and/or dispersed in the ink composition to achieve the targeted color and optical density are able to be used.

The elastomeric material is able to be an uncrosslinked elastomer, a thermoplastic elastomer, and/or a crosslinked elastomer. 
     In some embodiments, elastomeric materials suitable to be employed in a composition that is able to be used to form the compliant member  204  include, but are not limited to, natural rubber (NR), polyisoprene (IR), chloroprene rubber (CR), butyl rubber (BR), polybutadiene rubber (BR), nitrile rubber (NBR), styrene-butadiene rubber (SBR), ethylene propylene copolymer (EPDM), silicone rubber, ethylene-vinyl acetate (EVA), chlorosulfonated polyethylene (CSM), polyacrylic rubber (ACM), flourosilicone rubber, flouroelastomer, perflouroelastomer, polyether block amide (PEBA), chlorosulfonated polyethylene, thermoplastic elastomer, thermoplastic urethane, thermoplastic olefins (TPO) and/or thermoplastic vulcanizates (TPV). A person of ordinary skill in the art would appreciate that any polymeric materials are applicable so long as the polymeric materials have specific/selective adhesive property with the engineered surface. The polymeric materials are able to be polymers, co-polymers, graft polymers, blends, and elastomerics. 
     In some embodiments, the compliant member  204  is able to be formulated from silicone rubber. The silicone rubber is able to be formulated to produce compliant members  204  with a wide range of physical properties. A physical property of interest is the hardness of the compliant member  204 . The hardness of the compliant member  204  is able to be measured using a durometer using the ASTM 2240 type A scale. In contrast to the typical tacky pressure sensitive adhesive, the compliant member  204  formed from the crosslinked silicone rubber formulation is dry and non tacky to touch. 
     EXAMPLE A 
     Clear Compliant Member of Silicone 
     In a non-limiting example, a clear compliant member with a 16 Shore A is prepared using 100 parts Dow Corning 9600 base, 3 parts Dow Corning 9600 catalyst, and 3 parts Dow Corning SL 9106 coating. The components are weighed, mechanically mixed, formed to desired shape, and cured at 120° C. for one minute to produce a clear compliant member with a 16 Shore A hardness. 
     EXAMPLE B 
     Filled and or Colored Compliant Member of Silicone 
     In another non-limiting example, a colored compliant member is prepared using components from Example A. However, the Dow Corning 9600 base concentration needs to be adjusted proportionally to the masterbatch color added. For example, to produce a white compliant member a white masterbatch with 50% TiO2 is able to be added. The white masterbatch is available from Dow Corning LPX Liquid Color Masterbatches. If 24 parts of the white masterbatch is added, the Dow Corning 9600 base needs to be adjusted proportionally to 76 parts. Alternatively or additionally, color masterbatches are employed to produce a wide range of color. 
     EXAMPLE C 
     Conductive Compliant Member with Additions 
     In another non-limiting example, a conductive compliant member is prepared using components from Example A. Conductive materials, such as indium tin oxide, graphene, carbon nanotube, silver, copper, and/or gold nano-particles, are added to example A in effective concentration to produce conductive compliant member. The term “conductive” is able to include thermal, electrical, vibrational, signal, and/or for a purpose of antistatic. Other additives are able to include scents, molecular components, thermal indicators, various nanosensors, and biomaterials. Thin layers are able to be used to prevent outgassing of polymer components. 
     Silicone rubber is able to be employed to formulate compliant member with a range of physical properties. A catalyst such as platinum is able to be employed to increase curing rate and/or crosslink density of the rubber. Colorants are able to be employed to increase opacity of the compliant member and/or color the compliant member. Furthermore, conductive nano-particles are able to be added to form conductive compliant member. The compliant member formed from the silicone rubber formulation has the desired properties of dry, non-tacky, and compliance. 
     In some embodiments, the compliant member is able to be formulated from thermoplastic elastomer. The simplest thermoplastic elastomer consists of a rubbery midblock with two plastic polystyrene end-blocks. The thermoplastic elastomers comprises: polystyrene-polybutadiene-polystyrene polymers (S-B-S), polystyrene-polyisoprene-polystyrene polymers (S-I-S), polystyrene-poly(ethylene/butylene)-polystyrene polymers (S-EB-S), and/or polystyrene-poly(ethylene/propylene)-polystyrene polymers (S-EP-S). The thermoplastic elastomer is also able to be formulated to produce compliant members with a wide range of physical properties. The compliant member formed from the thermoplastic elastomer formulation is able to be dry and non-tacky to the touch. 
     Additives are able to be employed in thermoplastic elastomer formulation to affects end properties, e.g., Shore A. The choice of resin in the thermoplastic elastomer formulation is very important. There are two types of resin employed in thermoplastic elastomer formulation. The first type of resins is able to be mid-block-compatible resins, and the second type of resins is able to be end-block-compatible resins. 
     Mid-block-compatible resins have relatively low solubility parameters and tend to associate with the rubbery midblocks and not with the polystyrene end-blocks. The mid-block-compatible resins comprise: aliphatic olefin-derived resins, rosin esters, polyterpenes, and terpene phenolic resins. The effect of adding mid-block-compatible resin includes increasing the fraction of mid-block phase resulting in softening the compliant member, e.g., lower Shore A value. 
     End-block-compatible resins have relatively high solubility parameters and tend to associate with the polystyrene end-blocks and not with the rubbery mid-blocks. End-block-compatible resins are able to have softening points above about 85° C. The end-block-compatible resins comprise: polyaromatics, coumarone-indene resins, and other high solubility parameters resins. The effect of adding end-block-compatible resin includes increasing the fraction of end-block phase resulting in stiffening the compliant member, e.g., increase Shore A value. 
     In some embodiments, plasticizers are able to be employed in thermoplastic elastomer formulation to affect end properties of the compliant member. The desired characteristics of the plasticizers for thermoplastic elastomers include those that are completely insoluble with the end-block phase, completely soluble with the mid-block phase, and low in cost. The suitable plasticizers for thermoplastic elastomer formulation include hydrocarbon oils with solubility parameter slightly lower than the mid-block solubility parameter. The effect of adding plasticizer includes decreasing the hardness and modulus of the compliant member at room temperature, e.g., lower Shore A value. 
     EXAMPLE D 
     Thermoplastic Elastomer 
     In a non-limiting example, a clear compliant member is prepared using S-EB-S thermoplastic elastomer at about 70 parts, resin at about 25 parts, plasticizer at about 5 parts. The components are weighed, mechanically mixed, formed to desired shape to produce a clear compliant member. 
     Referring back to  FIGS. 1 and 2 ,  FIG. 1  shows that the particulate coating  104  is coated on the first surface  102 , so that the engineered surface  106  is formed. The engineered surface  106  is able to be a dry and/or non-tacky surface that is smooth in appearance and has no adhesive property, e.g., does not stick to itself or other surfaces.  FIG. 2  shows the compliant member  204  formed on the second surface  202  to form a compliant unit  206 . The surface of the compliant member  204  is able to be dry, non-tacky and has no adhesive property. 
     In some embodiments, the engineered surface  106  and the compliant unit  206  form an adhesive bond, in an unexpected and non-obvious manner, when the particulate coating  104  and the compliant member  204  are brought into physical contact. Since the surfaces of the engineered surface  106  and the compliant unit  206  are dry and non-tacky without adhesive property, the adhesion of the two surfaces to each other when in physical contact is an unexpected result. 
     The inventors herein believe that the adhesion mechanism is able to result from the formation of an adhesive mechanism between the compliant member  204  and the microscopic nano-pores that are formed on the engineered surface  106 . The engineered surface  106  is formed by applying a coating substance containing nano-particles on the first surface  102 . The nano-particles on the engineered surface  106  are separated by nano-pores due to imperfect packing. When the compliant member  204  comes into physical contact with the engineered surface  106 , the compliant member  204  is able to deform and fill in the nano-pores forming a mechanical interlocking adhesion mechanism. Furthermore, depending on the functional groups available, the adhesion from the mechanical interlocking is able to be and/or to be enhanced by hydrogen bonding and/or van der Waals force. The above mentioned functioning principle is described as one of the functioning principles and other functioning principles are also applicable. 
       FIG. 3  shows a simplified schematic of the adhesion formed between a compliant member  306  and a particulate coating  304  in accordance with one or more embodiments of the present invention. As shown in the example of  FIG. 3 , an engineered surface  301  comprises of first surface  302  which is able to be coated with the particulate coating  304  to form the engineered surface  301 . A compliant unit  303  comprises a second surface  308  which is able to be attached to the compliant member  306 . The engineered surface  301  with particulate coating  304  is in physical contact with compliant member  306  to form a novel adhesive bond to adhere the first surface  302  to the second surface  308 .

     Table III shows adhesion testing data of polyurethane strips of various Shore A hardness to the engineered surface. A set of polyurethane rubber strips are able to be obtained from Innovative Polymer, Inc. The data indicates that even for a high Shore A hardness value of 55, greater than 42 for silicone rubber, the polyurethane strips still show adhesion to the engineered surface. Thus the data indicates that different polymers are able to have different Shore A threshold value and still show adhesion to the engineered surface. 
       FIG. 4  is a flow chart illustrating a method  400  of forming and using a selective adhesive mechanism in accordance with some embodiments of the present invention.

A block  506  having an engineered surface  512  is able to be coupled to the block  504  by forming selective adhesion between the engineered surface  512  and the compliant member  510 . By adding block  506  to the first unit, the building block is able to continue to add on a second unit. Accordingly, the building block  500  is able to grow and extend infinitely. A person of ordinary skill in the art would appreciate that any numbers of the building blocks are applicable. 
       FIG. 6  shows uses of the surface specific polymeric dry adhesive  600  in accordance with some embodiments of the present invention. Similar to the building block  500  described above, the surface specific polymeric dry adhesive  600  is able to contain blocks  602  and  604 . The block  602  is able to contain an engineered surface and the block  604  is able to contain a compliant member  604 . The selective adhesion between the engineered surface of the block  602  and the compliant member  604  of the block  604  allows the blocks to be stacked up. For example, the block  606  with an engineered surface is able to attach to a side the block  608  with compliant member. Similarly, the block  610  with an engineered surface is able to be attached to the block  608 . The block  612  with a compliant member  612  is able to attach to the block  610 . The surface specific polymeric dry adhesive  600  is able to be molded/manufactured in any shape in 3D, applied to a 2D surface, or to be blended into the row material for making a product. Further, the surface specific polymeric dry adhesive  600  is able to be made with conductive materials, so that the building of the blocks  606  to  612  forms an electrical/thermal/signal/vibrational/signal conducting pathway from the block  606  to the block  612 . Furthermore, the surface specific polymeric dry adhesive  600  is able to comprise elastic/flexible materials, so that the blocks  606  to  612  are able to form a shock wave absorbing/reducing material and/or insulator. Moreover, the surface specific polymeric dry adhesive  600  is able to form a water-tight/seal device. The blocks  602 - 612  are described as some of the examples, a block  614  is able to have both the engineered surfaces  616  and compliant members  618  at any locations and/or zones. 
       FIG. 7  shows more uses of the surface specific polymeric dry adhesive  700  in accordance with some embodiments of the present invention. In some embodiments, the uses are able to comprise a polymeric unit  710  and a surface  701 . The surface  701  is able to contain the engineered surface as describe above forming a “smart surface,” “intelligent surface,” “intelligent material,” and/or “technical surface” with adjustable properties, such as adjustable adhesion by using the sprayable form of the coating substances for the engineered surface. In some embodiments, the surface  701  is able to contain a coated surface  702  using the coating substance/chemicals for the engineered surface described above. In other embodiments, the surface  701  is able to contain a material  704  blended with the substances for making the engineered surface described above. Accordingly, the substances for making the engineered surface and other materials are able to be blended/mixed thoroughly for making the material  704 . In some other embodiments, the substances for making the engineered surface are made into a sprayable form contained in a spraying container  708 , such as a pressurized canister with or without solvents. By having the sprayable form of the substances, the surface  701  is able to have a region  706  having the spray-on coating forming the engineered surface. In some embodiments, the surface  701  is able to contain different regions, such as the regions  702 ,  704 , and  706 , containing different properties, such as different density of the coating materials of the engineered surface or different graphic patterns. Additionally, the surface  701  is able to be treated with various other processes. For example, chemical processes are able to be used to selectively vary the Shore A hardness on the one or more of the regions  702 - 704  to create bonding or non-bonding areas. Further, plasma treatments are able to be applied to the surface  701 . In some embodiments, a tool  712 , such as a scissor, is able to be wrapped/coated with a layer of the polymeric unit  710 , such that the tool  712  is able to adhere to the surface  701 . 
       FIG. 8  shows more uses of the surface specific polymeric dry adhesive  800  in accordance with some embodiments of the present invention. The surface specific polymeric dry adhesive  800  is able to have various uses, including textile/clothing related applications, hair treatments, skin treatments, and making flexible electronics. 
     In some embodiments, a bra  810  comprises an engineered surface  812  in the inside cone of the bra, such that a breast pad  814  is able to be adhered and/or immobilized to the engineered surface  812 . A person of ordinary skill in the art would appreciate that the breast pad  814  is able to be made of silicone or any other polymers. In other embodiments, the bra  810  comprises a first strip with an engineered surface  818  and a second strip with a polymeric unit  820 , such that the bra  810  is able to be worn by attaching the engineered surface  818  with the polymeric unit  820 . 
     In some other embodiments, the substances/chemicals for making the coating of the engineered surface are made into a sprayable form. The substances are able to be non-toxic substances, such that the substances are able to be applied on human body or animals. The substances are also able to be PVP (polyvinyl pyrrolidone) resin or any other chemicals that are able to be used in hair products, such as gel and hairspray. The sprayable form of the substances is able to be contained in a container  804 . A user  802  is able to spray the substances on his/her skin  803 . A dress  806  having the surface specific polymeric dry adhesive  808  is able to adhere to the skin  803  preventing the dress  806  from slipping downward. The user  802  is also able to spray the substance on his/her hair  805 , such that a polymeric band  816  is able to adhere to the hair  805  for making a desired hairstyle. Similarly, the surface specific polymeric dry adhesive  800  is able to be used in many other objects using the components described above, such as jewelry, earrings, first-aid band aids, toupees, and false eyelashes. 
     Further, the surface specific polymeric dry adhesive  800  is able to be used in electronics, such as flexible electronics and printed circuit boards. In some examples, a polymeric unit, such as polyimide and PEEK (polyether ether ketone), is able to be used to adhere to conductor materials, such as copper wires, by applying the substances/chemicals for making the coating of the engineered surface. The substances mentioned above are able to replace/add on the typical bonding chemicals. 
     In a non-limiting example, the particulate coating is able to be applied onto a clean dry wall surface, a surface having primer thereon or a surface having paint thereon, of buildings to form an engineered surface. The wall that contains an engineered surface allows various articles attached to the compliant member to be adhered onto the wall. 
     In another non-limiting example, a shoe lace is able to be coated with the compliant member on one side of the lace and coated with the engineered surface on the other side of the lace. The shoe lace is able to be employed as a simple twist-tie to allow individuals without dexterity to adhere the end of the shoe lace together as simple twist-tie. Thus, the shoe lace is able to have both engineered surface and compliant member. In another non-limiting example, the material for making the engineered surface is used as a raw material or blended with other materials, such as plastics or gels, to make a substance containing the material for making the engineered surface. For example, the material for making the engineered surface is blended with pulp or cellulose to produce a sheet of paper. As a result, a portion or whole sheet of the paper is able to be selectively adhesive to an object that contains the compliant member or silicon rubber. 
       FIG. 9  shows a tape structure  900  using the surface specific polymeric dry adhesive in accordance with some embodiments of the present invention. The tape structure  900  is able to be rolled up as a tape roll. In some embodiments, the tape structure  900  comprises release liners  902  and  912 , pressure sensitive adhesives  904  and  910 , a compliance member  906 , and an engineered surface  908 . The release liner  902  is able to cover the surface of the compliance member  906  having pressure sensitive adhesive  904  in between the release liner  902  and the compliance member  906 . Similarly, the engineered surface  908  is able to be covered by the release liner  912  having the pressure sensitive adhesive  910  in between the release liner  912  and the engineered surface  908 . The release liners  902  and  912  are able to be peeled off allowing the pressure sensitive adhesives  904  and  910  attach/glue to substrates  914  and  916 . It should be apparent to those skilled in the art that the tape could also comprise a release coating instead of a release liner. The substrates  914  and  916  are able to be any substances, such as hand tools. By applying a part  918  (including pressure sensitive adhesive  910  and engineered surface  908 ) to the substrate  914  and a part  920  (including pressure sensitive adhesive  904  and the compliance member  906 ) to the substrate  916 , the substrates  914  and  916  are able to be instantly attachable to/detachable from each other. A person of ordinary skill in the art will appreciate that any number of layers are applicable. 
     To utilize the adhesive mechanism, a user brings the compliant member into physical contact with the engineered surface, so that the object containing the compliant member is able to instantly attach to the object that contains the engineered surface. To detach the compliant member from the engineered surface, the user is able to separate the compliant member with the engineered surface by a force. 
     In operation, the compliant member is able to be repeatedly attached to and detached from the engineered surface without substantial damages to the compliant member and the engineered surface.
