abstract: We report a method to form multifunctional polymer coatings through simple dip coating of objects in an aqueous solution of dopamine. Inspired by the composition of adhesive proteins in mussels, we used dopamine self polymerization to form thin, surface adherent polydopamine films onto a wide range of inorganic and organic materials, including noble metals, oxides, polymers, semiconductors, and ceramics. Secondary reactions can be used to create a variety of ad layers, including self assembled monolayers through deposition of long chain molecular building blocks, metal films by electroless metallization, and bioinert and bioactive surfaces via grafting of macromolecules.

abstract: Abstract Mussel inspired surface modification has been received great attention due to the universal adhesive properties of catechols for fabrication of multifunctional coatings, especially for gluing hydrophilic polymers to fabricate underwater superoleophobic materials utilizing in oil/water separation. Despite the extensive research carried out on this topic, the similarity and discrepancy between catecholamine and catecholic amino acid on surface modification and post functionalization have not been fully addressed yet. In this work, underwater superoleophobic surfaces have been successfully developed by a two step dip coating method with mussel inspired coatings and subsequent zwitterionic sulfobetaine methacrylate (SBMA) grafting onto stainless steel meshes and used in oil/water separation. Here, dopamine and 3,4 dihydroxy L phenylalanine were both served as mussel adhesives. More specifically, small molecule zwitterion rather than polyzwitterion was functionalized onto mussel inspired coatings to minimize the effect of surface topography on surface wettability. The modified surfaces were characterized by scanning electron microscopy (SEM) atomic force microscopy (AFM) and contact angle measurements to observe the surface morphology, estimate the surface roughness, and evaluate the wettability, respectively. It showed that SBMA modified meshes with polydopamine (PDA) or poly(3,4 dihydroxy L phenylalanine) (PDOPA) layer possessed quite different surface roughness, while both presented excellent oil repellency in water with underwater oil contact angles of 153deg 160deg, indicating a less dependence on surface roughness. Although by using the small molecule as the hydrophilic functionalized groups, the as prepared meshes exhibited good self cleaning and oil/water separation performance (separation efficiency >98% for hexane and >97% for soybean oil) and outstanding recyclability with 98% separation efficiency after 30 cycles. This method provides insight into different properties of polycatechols and simplifies the fabrication process through the use of small molecule zwitterion rather than zwitterionic polymer. Besides, the modified meshes also exhibited excellent stability for long term use. The resulting underwater superoleophobicity and robust self cleaning ability promise an ideal candidate for oil/water separation and oil contamination restriction.

abstract: Heparin, an important polysaccharide, has been widely used for coatings of cardiovascular devices because of its multiple biological functions including anticoagulation and inhibition of intimal hyperplasia. In this study, surface heparinization of a commonly used 316L stainless steel (SS) was explored for preparation of a multifunctional vascular stent. Dip coating of the stents in an aqueous solution of dopamine and hexamethylendiamine (HD) (PDAM/HD) was presented as a facile method to form an adhesive coating rich in primary amine groups, which was used for covalent heparin immobilization via active ester chemistry. A heparin grafting density of about 900 ng/cm(2) was achieved with this method. The retained bioactivity of the immobilized heparin was confirmed by a remarkable prolongation of the activated partial thromboplastin time (APTT) for about 15 s, suppression of platelet adhesion, and prevention of the denaturation of adsorbed fibrinogen. The Hep PDAM/HD also presented a favorable microenvironment for selectively enhancing endothelial cell (EC) adhesion, proliferation, migration and release of nitric oxide (NO) and at the same time inhibiting smooth muscle cell (SMC) adhesion and proliferation. Upon subcutaneous implantation, the Hep PDAM/HD exhibited mitigated tissue response, with thinner fibrous capsule and less granulation formation compared to the control 316L SS. This number of unique functions qualifies the heparinized coating as an attractive alternative for the design of a new generation of stents.

abstract: Mussel inspired chemistry has been broadly exploited for multifunctional coatings in the surface modification of applied materials. Polyphenols are ubiquitous in plant tissues and far less expensive than polydopamine for mussel inspired chemistry. Herein, we report a facile and effective method to modify porous membranes via the co deposition of catechol (CCh) and polyethyleneimine (PEI) The membrane structures and properties were investigated by ATR/FTIR, XPS, FESEM, zeta potential, water contact angle and pure water flux measurements. The results reveal that the membranes deposited with a CCh PEI mass ratio of 1:0.25 show excellent hydrophilicity, ultrahigh water permeation flux and distinguished surface charges. These membranes were used to decolorize anionic dye solutions during filtration with superior removal efficiencies of over 99% Moreover, they have good reusability over repeated operations with a simple regeneration process.

abstract: Abstract Plant inspired polyphenols are capable of forming substrate independent coatings for versatile functionalization via oxidative self polymerization in an alkalescent aqueous solution. However, shortcomings like low uniformity and lengthy reaction times discourage their large scale implementations. In this work, we report a benign surface modification method for the highly effective, inexpensive construction of catechol (CA) coatings using sodium periodate (SP) as a trigger. Compared with recent progress in polyphenol coatings, our strategy achieved by far the fastest superhydrophilic modification rate ever reported. UV vis spectroscopy, atomic force microscopy (AFM) and ellipsometry are used to gain insights into the reaction kinetics of oxidant triggered polymerization and deposition of CA. SP assisted CA films with good homogeneity were efficiently deposited on various dense and porous substrates. Ultimately, the unprecedentedly superhydrophilic/underwater superoleophobic coating layer was applied on the initially hydrophobic polyvinylidene fluoride (PVDF) membrane, endowing the porous membrane with extremely high pure water permeability, favorable heavy metal adsorption ability, and outstanding oil/water separation performance. Due to the chemical versatility of CA, we envision that this novel coating technique holds significant potentials in tailoring the surface properties of different materials for a wide range of applications.

With the rapid development of this field, more flexible and efficient modification strategies for surface engineering and application modes have been developed recently. It is therefore critical to update the broader scientific community on the important advances in this interdisciplinary field. Here, we summarize recent progress in mussel inspired chemistry and its emerging applications in water remediation. The reaction and adhesion mechanisms of polydopamine, as well as its chemical and physical properties, are discussed. The functionalization strategies are categorized into post functionalization, co deposition, and pre modification, and the roles of mussel inspired surface coatings are highlighted in filtration, adsorbing, and catalytic materials as well as the burgeoning area of photothermal distillation materials.

abstract: In this work, surface functionalized microcapsules from porous carbon nanospheres (PCNs) were successfully prepared by mussel inspired chemistry with polydopamine (PDA) and metal free photoinduced electron transfer atom transfer radical polymerization (PET ATRP) These functional microcapsules are introduced into self healing hydrogels to enhance its mechanical strength. The PCNs synthesized by a simple soft template method are mixed with linseed oil (LO) for loading of the biomass healing agent and the microcapsules are first prepared by coating PDA. PDA coatings were used to immobilize ATRP initiator for initiating 4 vinylpyridine (4VP) on the surface of microcapsules by PET ATRP. Using these functional microcapsules, the self healing efficiency was about 92.5% after 4 hrs at ambient temperature and the healed tensile strength can be held at 2.5 MPa with a fracture strain of 625.2% All results indicated that the surface functionalized microcapsules for self healing hydrogels have remarkable biocompatibility and mechanical properties.
