## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is the U.S. National Stage of International Application PCT/KR02/00311, filed Feb. 26, 2002, which in turn claims priority from Korean Patent Application 2001/14519, filed Mar. 21, 2001.
TECHNICAL FIELD OF THE INVENTION
The present invention relates to conductive polymers, and more particularly it relates to an additive for enhancing electrical conductivity of the conductive polymer which forms a conductive polymer composition with said additive.
DISCUSSION OF RELATED ART
Most conductive polymers show a strong tendency to polarize and have commonly conjugated double bond that makes an inter-molecular force remarkably strong by dispersion force among electrons. By moving charges through doping step which adds an electron donor or an electron acceptor, the polymers get to conductive polymer salt with conductive values of over 10−8 S/cm.
The conductive polymers are applicable as an EMI shielding material, an antistatic material, an anticorrosive material, a static discharge material, and the like.
The advantage of the conductive polymers is that they can be variously processed, can be lightweight, and can be produced in commercial quantities.
Polyacetylene, known as the first conductive polymer, has a disadvantage of its easy oxidation in the air, and it was followed by the development of polyaniline, polypyrrole, polythiophene, and the like.
Polyaniline is especially attractive because it is not only relatively inexpensive and chemically very stable but also easily proton doped.
The polyaniline can be classified into leuco-emeralidine, completely reduced form, emeraldine, partly oxidized form, and pernigraniline, completely oxidized form, in accordance with its oxidation state.
Because the completely reduced form and completely oxidized form of polyaniline have high melting points, they cannot be processed in melt processing. Also they cannot be easily processed because they have low solubility in solvents with high boiling point such as meta-cresol and in general purpose organic solvents.
To resolve these disadvantages, it had been tried to improve both processability and conductivity by synthesis of graft-copolymers or its derivatives into which various side chains backbone of the conductive polymer is induced for enhancing the dissolution. But these compounds have a much lower electrical conductivity than the conductive polymer before reforming.
Many studies described in patents and articles have demonstrated increased proccessability and conductivity by adding various organic materials, polymers or plasticizers.
Among those, a method, which became a turning point for increasing processability and conductivity of conductive polymers, used organic sulfonic acid such as camphorsulfonic acid (CSA) or para-dodecylbenznenesulfonic acid (DBSA) as a dopant of the conductive polymers.
After that many patents relating to improving conductivity of conductive polymers are issued. Among those patents, U.S. Pat. No. 6,099,097 and U.S. Pat. No. 6,123,883 proposed methods for processing which add gel inhibitors such as second amines into polyaniline to prevent its gelation resulted from intermolecular hydrogen bond dissolving high molecular weight polyaniline, if said polyaniline is in an amount of more than 15% by weight to manufactured fibers.
But, the above two U.S. patents have a complex and costly processing procedure because they require separately adding the second additives which do not make an effect on increasing electrical conductivity of the conductive polymers.
U.S. Pat. No. 5,407,505 describes another processing method of polyaniline. This patent proposed liquid composition comprising of a strong acid solution containing polyaniline in which other polymer such as polypara-(phenylene terephthalamide) were dissolved or a solid composition comprising crystalline polyaniline dissolved in acids. However, polyaniline was not easily processed because of dissolving in strong acid, and electrical conductivity was decreased because of the unwanted reactions followed in dissolving procedure, and also the polyaniline have lower conductivity than pure polyaniline owing to adding polypara-(phenylene terephthalamide).
U.S. Pat. No. 5,882,566 describes a method of manufacturing electrically conductive fiber with high tension and high modulus using polypara-(phenylene terephthalamide). But the polymer in this patent is also manufactured by dissolving it in sulfuric acid and thus the polyaniline itself has a sulfonic functional group. As a result the polyaniline has a disadvantage that its conductivity is reduced as described above. This patent also describes a composition comprising polypara-(phenylene terephthalamide) wherein polyaniline has higher electrical conductivity than polyanilene salt form produced from sulfonated reactants, but the electrical conductivity of the composition comprising polypara-(phenylene terephthalamide) showed 10−3 ̃2.0 S/cm, that is much lower than that of a pure polyaniline salt.
U.S. Pat. No. 5,863,658 reported conductive polymers manufactured from polymer with rigid rod form of aromatic benzazole and polyaniline increased electrical conductivity to 128 S/cm. But these polymers seem to be applicable to specific use such as film application because aromatic benzazole polymer and the polyaniline can be dissolved in only a strong acid such as methane sulfonic acid. Accordingly, rigid rod form polymers have very high thermal stability and mechanical properties, but they are difficult to melt and have a low solubility in solvents.
Besides the patents described above, a lot of research results relating to conductive polymers were described in detail in a number of publications (Organic conductive molecules and Polymers Vol. I–IV, Ed. by H. S. Nalwa, John Wiley & Sons, New York. 1997, Handbook of Conducting Polymers Vol. I, II, Ed. by Skotheim et. al. Marcel Dekker, N.Y. 1998, Conductive Polymers, P. Chandrasekhar, Kluwer Acade. Pub. Boston. 1999).
Thus by reviewing a prior art related to enhancement of the conductivity of the conductive polymers in the patents described above and various reports, it is concluded that the conductive polymers still do not have high enough electrical conductivity and processability for industrialization.
Conductive polymers have different applications according to electrical conductivity. That is, conductive polymers having the electrical conductivity of 10−13 ̃10−7 S/cm, 10−6 ̃10−2 S/cm, or more than 1 S/cm are applicable to antistatic materials, static discharge materials, or EMI shielding materials, and semiconductors or solar batteries, respectively. Accordingly upon enhancing the electrical conductivity of the polymers, they can be used in more applications.
Consequently, conductive polymers including polyaniline w are limited to extremely limited field, therefore, increasing electrical conductivity and processability of the polymer are needed for various developments of expanding their use.

DETAILED DESCRIPTION OF THE INVENTION
The additives for a conductive polymer, with above objects, of the present invention contain a monomer induced with a flexible side chain having various polarities or hydrophilic dibasic acid to aromatic ring, a complex linked by hydrogen bond or metal coordinate bond among the monomer, or a whole aromatic polyamide or a polyester linked repeatedly with —NRCO—, —NROSO—(R is side chain including hydrogen), and —CO—. The monomer, complex, polyamide or polyester are linked to aromatic ring above, respectively.
The additives are based on rigid rod-form polymer self-assembled by hydrogen bond among hydrophilic functional groups or linked not only by metal coordinate bond but also by —NRCO—, —NROSO— or —OCO—. By inducing flexible long side chain into the aromatic ring of the polymers, it provides amphiphlicity and possibility of transforming of the conductive polymer with improved solubility and compatibility, as described in U.S. Pat. No. 5,470,505.
After substituting rigid backbone with normal alkyl group of less than 20 of carbon atoms as an flexible side chain, its mechanical, thermal and physical properties were initially investigated by Lenz et al. (Lenz; Eur. J. Polym. 19, p 1043, 1983) and developed by Ballauff (Ballauff et al, Angev. Chem. Int. Ed. Engl. 28, 253, 1989).
The present inventors discovered the following results. On substituting side chain (i.e. lengthy alkyl alike) to aromatic dibasic acid, the hydrophilic and/or hydrophobic functional groups in monomer had amphiphlicty and self-orientation to form intermediate phase like liquid crystal and have orders. Accordingly, inducing these monomers into conductive polymer, according to the present invention, can change the chain form structure of the polymer.
Based on the fact mentioned above and taking into account of interaction the conductive polymer, a soluble self-orienting materials (SOM), substituted with various types of side chains with a carbon number 6 ̃30 independently/coordinately to the aromatic ring was synthesized. The SOM was made up of a monomer/polymer leading self-orientation and was able to be synthesized through a simple organic polymer reaction.
For example, an aromatic dibasic acid (General formula 1 below) monomer and its metal-salt (General formula 2 below) was produced from synthesizing a monomer through simple organic substitution reaction and then reacting between this acid and metal oxidized material/metal chlorinated material. And polymer (general formula 3 below) could be produced from a condensation reaction between carboxylic acid and 1,4-phenylendiamine or hydroquinone having substitution group.




wherein p, q, or r in General formulas 1, 2, 3, respectively, are positive integers; X1 and X2 in General formula 1 are independently selected from —SO2OH or —COOH; X1 and X2 in general formula 2 are independently selected from —CO2 or —SO3. X and X2 in general formula 3 are independently selected from —O—, —NR—, R is independently selected from —H, —SO3H, —COOH, —(CH2)nSO3H, —(CH2)nCOOH and tert-butyloxycarbonyl; A1 is an aromatic ring and independently selected from phenyl, naphthyl, biphenyl (Φ—Φ; Φ=C6H5), benzophenone (Φ-CO-Φ), benzanilide (Φ-CONH-Φ), phenylether (Φ-O-Φ), phenylsulfide (Φ-S-Φ), phenylsulfone (Φ-SO2-Φ), or phenylsulfoneamide (Φ-SO2NH-Φ); A2 in General formula 3 is a secondary aromatic ring independently selected from pure/sulfonated phenyl, naphthyl or biphenyl;

M in General formula 2 is an alkali or transitional metal cation, which can be independently selected from monovalent cation, particularly Li+, Na+ or K+, or a small bivalent cation like Cu2+, Zn2+, Cd2+, Mg2+, Pb2+, Mn2+, Fe2+ or Ca2+. Also it can be Fe3+, Ti4+, Zr4+ or Mn7+; and
Z1 and Z2 in General formula 1, 2, or 3 and Z3 and Z4 in General formula 3 above are independently selected from two types of side chain below.
The first side chain is a group inducing stable doping and the second side chain is a group having affinity with cation or helping movement of charges.
More specifically, substituted groups Z1, Z2, Z3, and Z4 are independently selected and at least one of them contains carbon (C) or nitrogen (N), sulfur (S) and oxygen (O) as a hetero atom. Preferably the groups contain a side chain of alkyl, alkenyl, alkynyl, or alicyclic derivatives such as norbonene comprising one of —(CH2)nCH3, —O(CH2)nCH3, —O(CH2)nCH3, and —O(CH2CH2)nOCH3 (n is an integer 1 ̃24) with a total length of the side chain of 2 ̃30, preferably 6 ̃24.
Also, terminal end of Z1, Z2, Z3 and Z4 may be selected from the side chains attached to sulfonic acid (—SO3H), carboxylic acid(—COOH), and benzenesulfonic acid(—OC6H4SO3H) or azacrown ether, carbazole, thiol (—SH), pyridinium, imidazol, and benzimidazol, which have 6 ̃24 aromatic rings, for stable doping or affinity with cation and charge movement. Especially, self-orienting material attaching pyridinium, imidazol, and benzimidazol to the terminal end of the side chain is multi-functional material with a function of a gel-inhibitor, for transferring of stable cation and dopant and also designed for enhancing electrical conductivity and compatibility.
According to the present invention, upon inducing carboxylic group or sulfonic acidic group along with the flexible matrix side chain such as simple alkyl into the rigid aromatic ring, these molecules generally are self-assembled and oriented to form order in a definite concentration resulted from amphiphilicity.
In the polymer described by General formula 3, it is desirable that the carboxylic group or the sulfonic acidic group contained in the side chain is in the range of 1 ̃15% by weight based on the total polymer weight and have a number average molecular weight of 4,000 ̃100,000.
Not only can the SOM of the polymer function be a self-orienting material, it also can be a dopant simultaneously by inducing carboxylic group or sulfonic acidic group into it, thus it can blend with the conductive polymer without another dopants.
Also, if the cross-section of a hydrophilic molecule and of an alkyl group in the amphiphilic molecule is almost the same, a layered structure is stabilized and the SOM functions as a surfactant. As a result, the problem of insolubility and unprocessability caused by rigid chain form of the conductive polymer can be solved, as well as electrical conductivity by inducing chain straightly can be improved, by applying the SOM to the conductive polymer and extending the concept of a liquid crystalline phase or a crystalline phase with layer.
For example, if whole aromatic polyamide, which is insoluble and unmeltable, is substituted with two types of flexible matrix side chains above to its benzenic ring, it can be soluble in organic solvents such as 1-methyl-2-pyrrolydinon, 1,1,2,2,-tetrachloroethane, chloroform, and meta-cresol, form liquid crystalline phase, and meltable as a result of increasing thermal fluidity.
Accordingly, a polyamide polymer as the SOM of the present invention, which is a rigid polymer of an aromatic backbone structure linked repeatedly with —NRCO— and —NROSO— between 2 benzenic ring substituted by long side chains, unlike polyparaphenylene terephthalamide (U.S. Pat. No. 5,470,505; U.S. Pat. No. 5,882,566) without side chain, is a polymer material having an advantage showing thermal melting behavior because it can be solved well in ordinary organic solvents.
The polyamide polymer of the present invention, with relatively relieved interaction such as an intermolecular hydrogen bond by a self-orient effect of the side chain, has a property to increase an interaction like the hydrogen bond with the conductive polymer. So, it has increasing compatibility and prevents gelation by the hydrogen bond between polyaniline molecules. As a result, it has advantage of decreasing preparation procedure and cost because other additives such as gel inhibitor are not needed for processing.
The SOM above has an ultimate object of maximum electrical conductivity in contained quantity by designing the length of type of the side chain in the aromatic backbone properly and increasing solubility and compatibility, said backbone can be changed a bit. It is possible that both the polymer linked only to para-position with an at least long side chains and a terpolymer comprising 1 ̃30% molar ratio of an unbranched monomer such as para-phenylenediamine, terephthaloylchloride, or 2,6-naphtoylchlride are alike Soluble self-orienting polymers.
These terpolymers refer to a linear polymer which links benzene rings as a monomeric unit at only para position or refers to a linear-curved copolymer which links benzene rings at meta or ortho position together with para position. It is well known that melting processibility, solubility and the like of these linear-curved copolymers increase generally unlike those of the linear copolymers, which link only para position. The present invention also contains a composition comprising the linear polymer linked monomeric units at only para position and with the linear-curved copolymer in order to optimize process procedure although the copolymer makes electrical conductivity low.
Electrically conductive polymer according to the present invention suitable for enhancing electrical conductivity contains polyaniline, polypyrrole, polythiophene, polyacetylene, poly-para-phenylene, polyphenylenesulfide, polycarbazole alike, especially in doping the conductive polymer of the present invention by a proton such as polyaniline, polypyrrole, polythiophene even without other dopants. By inducing the SOM of the present invention, the electrical conductivity of the conductive polymer by inducing chain form of dopant and of the conductive polymer can be increased linearly. Also, because the SOM can enhance solubility, it can apply to any reformed conductive polymer, such as conductive polymer with substitution group or other additives.
Although it is desirable that SOM in molecular weight or in quantity used regularly up to property or use of conductive polymer, it has self-orienting property as mentioned above and it has no limited molecular weight, it can be 1 ̃99% in quantity.
But, in the SOM of polymeric form, as mentioned above in general formula 3, its interaction with the conductive polymer has an important meaning in molecular weight or distribution of molecular weight because terminal end of aromatic backbone is primary amines or carboxylic acid.
For example, in case the number average molecular weight of the conductive polymer is less than 5000, and enhancing processability and physical property resulted from increasing molecular weight of the SOM by more than 0.2 g/dL of intrinsic viscosity, the effect of terminal end decreases relatively. But in case the number average molecular weight of conductive polymer is over 10,000, still more than 30, 000 in range of allowable mechanical, physical properties, we can lower molecular weight or contained quantity of the SOM above. In this case, the role of terminal end is relatively large. But, to maximize electrical conductivity, it is desirable that we raise contained quantity of the SOM by more than 50%, preferably by more than 85%, by using various types of SOM respectively.

BEST MODE FOR CARRYING OUT THE INVENTION
We will explain in detail the SOM and processing method of its composition of the present invention through a desirable example.
To begin, a method to measure electrical conductivity and a method to process by synthesizing polyaniline into emeraldine base as a conductive polymer are described.
<Method to Measure Electrical Conductivity>
Electrical conductivity is measured by a four-line probe method in room temperature with a relative humidity 50%. We used carbon paste for contacting gold wired electrode, and measured electrical current, two external electrodes, and voltage from filmic sample (thickness: t, width: w) with a thickness of 1 ̃10 μm, and electrical conductivity with regard to distance (1) between two internal electrode with Keithley conductivity measurement apparatus. Electrical conductivity was calculated by the formula below, and units of electrical conductivity are in Siemen/cm or S/cm.

Electrical Conductivity=(l×i)/(w×t×v)

We measured by Van der Pauw method, which is a standard four point probe, for certifying equality of electrical conductivity in samples, but they matched within 5% in result.
<Process for Synthesizing Polyaniline Emeraldine Base>
Polyaniline emeraldine base was synthesized by Mcdiarmid method (Mcdiarmid et al; conducting Polymer Ed. by Alcacer, Dordrecht, 105, 1987).

Then the solution was treated with a jetting method, which is scattering water and ethanol with a ratio of 3:1 with injection syringe (needle gauge 20), to manufacture monofilament.

EXAMPLE 14
Example 14 is with regard to manufacturing of the quaternary polyaniline-SOM composition and to thin-film manufacturing.
Into a 500 ml, 3-necked flask was placed the solution dissolved in ethanol 200 ml and was stirred. The solution was neutralized with Ca(CO)3 0.5 g. After mixing polyaniline 4 g and PAA 4 g into the neutralized solution with the same procedure as Example 9, the mixture was precipitated and filtered to obtain a filter cake. After drying the filter cake 8 g and nylon 6 (Toplomid 1011R, Hyosung T&C) 12 g at 80° C. for 24 hours, they were mixed at 240° C., 50 rpm using the Haake Mixer. This mixture was compressed at 235° C. to manufacture the sheet sample with a thickness of 10 μm. These samples had tensile strength of 70 MPa and electrical conductivity of 0.2 S/cm after doping them with 0.5M carboxylic acid and sulfonic acid monomer.
Besides, the electrical conductivity of the sample of polyaniline emeraldine salt with 1M hydrochloride solution in the absence of particular additives with that of the sample of the film form of the polyaniline composition mixing conductive polymers, which with the induced SOM of a monomer according to the present invention, and with polyaniline of 15% by weight were 2 S/cm and 1,240 S/cm respectively, that is 620-fold. However, if the contents of polyaniline were less than 15% by weight, the polymers had lower electrical conductivity than pure polyaniline emeraldine salt. It means that the SOM is closely connected with adjusting of a composition ratio of polyaniline.
Accordingly it is possible for the composition of the present invention, which is mixed with SOM and a conductive polymer, to have the electrical conductivity of 10−8 ̃103 S/cm in accordance with contents of the conductive polymer.
That is, the conductive polymer composition containing the SOM of the present invention make SOM occupy 1–95% by weight, desirably 5–85% and more desirably 15–70%, and maintain the range of the above conductivity.
The conductive polymer composition containing SOM of the present invention through above Examples have a function as a dopant and self-orienting promoter. But the present invention is not limited to the above Examples and may be applied to other forms without departing from the essential characteristics thereof.
The conductive polymer composition consisting of the SOM of the present invention can be applied to processing of films, fibers, coatings and the like by precipitating a solution-state composition into other liquids such as water and by vaporizing solvents of the solution using a processing apparatus. Also, the conductive polymer can be processed in the mater-batch form in a solution state or a melting state responding without or with the second polymer using extruder, injector, or Brabender. Because electrical conductivity of the processed polymer is increased by spinning rate of screws resulted from properties of self-orientation and the like of the SOM, those properties can be used effectively only if the most suitable conditions are satisfied.
Various metals can be used with used polymers and solvents depending on temperature and composition of polymers. For example, the SOM containing Zn can be used without any difficulties owing to melting over typical processing temperature of 220° C. and the SOM containing Ca is not dissolved over 270° C., but it can be used because it is dissolved in a mixed solvent such as hydriquinone and so forth.
Particularly, on coating the composition into steel, Ni, Al, Cu, Zn, Co, Pb, No, Nb, Ag, Ta, Ti, Zr or alloy of steel for anti-corrosion, that dopants have an anti-corrosive effect resulting from the passivating anodic sites of acids attached to side chain of the composition.
INDUSTRIAL APPLICABILITY

So it can be used to all sorts of conductive film, fiber, coatings, polymer blending, battery electrode or organic semiconductor. And the composition has high electrical conductivity notwithstanding low contents of conductive polymers. So it is suitable for the particular use such as transparent electrode, anti-corrosion, near-infrared light absorption, conductive etch mask layer and so forth.
The SOM comprises aliphatic compounds, which are self-assembled to thin film by langmuir-blogett molecular assembly as mixed agent of conductive polymer in addition to interfacial active agent. After being self-assembled, it can be applied to opto-electronic materials according to the pattern of the side chains too.
Besides, the SOM has high interfacial adhesion and fusibility and as a result it can be adapted to various products made by general processing for thermoplastic resins such as a template for making a model of nano-particle inorganic materials or fiber, film and coatings requiring conductivity.
