Abstract: Disclosed is an electron-conductive high polymer, which has at least (1) an ethylenic repeating unit having an electron-conductive site comprising at least one of aniline compounds and heterocyclic compounds as the repeating unit in the side chain and (2) an ethylenic repeating unit having an anionic group in the side chain and/or an ethylenic repeating unit having a repeating unit of an oxyalkylene group in the side chain. As having excellent electroconductivity, mechanical strength and shapability, the high polymer is laminated with a solid polyelectrolyte or with a separator to prepare an electroconductive material usable as a battery material.

Description: FIELD OF THE INVENTION The present invention relates to an electroconductive material which may widely be utilized in various fields of antistatic materials for plastics, electric industrial materials, electronic industrial materials, such as electrodes or electrolytic materials for batteries, condensers, electronic devices and electrochromic elements, as well as plane heaters and electromagnetic shielding materials. BACKGROUND OF THE INVENTION Organic high polymer materials having an electron-conductivity have recently been investigated as to the applicability thereof to batteries and other various functional devices. For instance, polyaniliens, polythiophenes, polypyrroles, polyphenylenevinylenes, polyphenyleneacetylenes and polyacetylenes are considered to be hopeful, and these are described in West German Patents 3,223,544, 3,318,856, 3,318,857, 3,325,892, 3,338,904 and 3,421,296 and JP-A-58-187432, JP-A-59-43060, JP-A-59-112583, JP-A-58-209864, JP-A-59-207933, JP-A-60-120722, JP-A-60-67527, JP-A-62-225518, JP-A-62- 53328 JP-A-63-199726, JP-A-60-223817, JP-A-61-83221 and JP-A-59-31565. (The term "JP-A" as used herein means an "unexamined published Japanese patent application".) Although these high polymers have an excellent electron-conductivity, they have some drawbacks that the mechanical strength is poor, and since the solvent-solubility is poor, the moldability and workability is poor. Therefore, electron-conductive high polymers having both an excellent electron-conductivity and an excellent moldability and workability are desired. An electroconductive material now in use is composed of the above-mentioned electron-conductive high polymer and an electrolyte in the form of a layer. In such constitution, exchange of electron for ion at the interface between them is to be effected rapidly in order that the device or battery may sufficiently function. As the electrolyte, a solid polyelectrolyte is preferred in view of various points that it is free from leakage of liquid, the mechanical strength is large and the flexibility of the laminate material is large. Various reports of using such a solid polyelectrolyte in the constitution of an electroconductive material have been made up to the present. For instance, as one example of an electroconductive electronic material comprising a combination of such a solid polyelectrolyte and an electron-conductive high polymer, POLYMER , 1981, vol. 22, November, pages 1454 to 1455 has disclosed an organic battery comprising a combination of a polyacetylene and a solid electrolyte. However, the battery has various problems that the film of polyacetylene as prepared by addition polymerization has a poor oxidation stability, the contact at the interface of the solid polyelectrolyte is insufficient so that a good electroconductivity could not be obtained, and the response speed is slow as a device material. JP-A-62-98577 has disclosed an electroconductive laminate material comprising a combination of a high polymer having a conjugated double bond in the electrolytic polymerized main chain and a solid polyelectrolyte. However, the material also has various problems that the interfacial contact between the electron-conductive high polymer and the solid polyelectrolyte is insufficient and therefore the interfacial resistance is large and the electroconductivity of the material is not good and additionally the mechanical strength of the material is poor. As a compound which may have both a sufficient mechanical strength and a good electroconductivity, polymers having a carbazole group-containing repeating unit in the side chain, for example, a compound of a formula: were discussed in 37th High Polymer Discussion Meeting 2H04. However, the electroconductivity of the compound was from 10⁻⁴ to 10⁻⁵ S/cm and is therefore insufficient. Where a polyaniline or polyheterocyclic compound is used as an electrode material, anions are doped or disdoped along with the redox reaction. Takehara et al. (56th Meeting of Electrochemical Association, 3G24) have reported that the diffusion of anions is conducted at a determining speed in the procedure. As a means of preventing the diffusion of anions, one example has been illustrated in JP-A-63-215772, where an anionic compound is used as a doping agent. However, the method has been found to disadvantageously cause the concentration gradient of the anionic compound because of the diffusion thereof after repeated doping. Therefore, the method could not be a sufficient improving means. SUMMARY OF THE INVENTION The first object of the present invention is to provide an electron-conductive high polymer having an excellent electron-conductivity, a high mechanical strength and an excellent moldability and workability. The second object of the present invention is to provide an electron-conductive high polymer which may rapidly be doped and disdoped with anions in a redox reaction of the polymer. The third object of the present invention is to provide an integrated electroconductive material composed of an electron-conductive high polymer and a solid polyelectrolyte, which has low resistance at the contact interface, an excellent electric conductivity and a rapid response speed as a device material. The fourth object of the present invention is to provide an electroconductive material using an electron-conductive high polymer which additionally has a function of a solid polyelectrolyte, and thereby an electrolyte layer becomes unnecessary. The objects of the present invention have been attained by an electron-conductive high polymer which has at least (1) an ethylenic repeating unit having an electron-conductive site comprising at least one of aniline compounds and heterocyclic compounds as the repeating unit in the side chain and (2) an ethylenic repeating unit having an anionic group in the side chain and/or an ethylenic repeating unit having a repeating unit of an oxylalkylene group in the side chain, and by an electroconductive material having the electron-conductive high polymer.

For producing the electron-conductive high polymer of the present invention, any known production methods may be employed. For example, the polymer may be produced by a known polymerization method, chemical oxidative polymerization method, electrolytic oxidative polymerization method, or C-C coupling reaction method. As one example, polymerization of the main chain is first effected so that the resulting polymer may have an electron-conductive site in the side chain and anion groups and/or repeating units of oxyalkylene group in the side chain, and then the electron-conductive site is polymerized by chemical oxidative polymerization, electrolytic oxidative polymerization or C-C coupling reaction to obtain the compound of the present invention. In the process, the latter polymerization may be effected at different electron-conductive sites. As another example, polymerization of the electron-conductive site is first effected by chemical oxidative polymerization, electrolytic oxidative polymerization or C-C coupling reaction and then the side chain having the electron-conductive site-repeating units may be introduced into the main chain of the polymer having anion groups and/or repeating units of oxyalkylene group in the side chain, by high polymer reaction. As still another example, polymerization of the main chain may be effected by the use of prepolymers obtained by polymerization of electron-conductive sites by chemical oxidative polymerization, electrolytic oxidative polymerization or C-C coupling reaction, and monomers having anion groups in the side chain and/or monomers having repeating units of oxyalkylene group in the side chain. In the process to obtain the electron-conductive high polymer of the present invention, the polymerization of main chain may be carried out by copolymerization with any monomers other than monomers to provide repeating units of electron-conductive site in the side chain, and monomers having anion groups in the side chain and/or monomers having repeating units of oxyalkylene group in the side chain. The above-mentioned chemical oxidative polymerization is effected by dissolving or dispersing a monomer compound in water or in any desired organic solvent (which may optionally contain water) and then gradually and dropwise adding a solution containing a catalyst (oxidizing agent) to the resulting solution or dispersion at 60°C to -20°C, preferably at 20°C to 0°C. In the case, a pertinent dispersing agent or surfactant may be employed to give an aqueous dispersion containing the polymer formed. The polymer thus formed preferably has an excellent moldability and workability. The above-mentioned electrolytic oxidative polymerization is effected by a constant voltage method, constant potential method or constant current method, where a monomer compound and a conductive salt are dissolved or dispersed in water or in an organic solvent capable of dissolving the conductive salt, and positive and negative poles are dipped in the resulting solution or dispersion at 80°C to -20°C, preferably at 30°C to 0°C. Preferred is the constant voltage method, as is disclosed in Conductive High Polymer , page 72, edited by Naoya Ogata, published by Kodansha Scientific (1990). The above-mentioned C-C coupling reaction is essentially applied to thiophene compounds, though it may also be applied to aniline compounds and pyrrole compounds. For instance, a halogenated thiophene compound is reacted with a Grignard reactant or a metal halide to obtain the compound of the present invention. The reaction is concretely described in, for example, Synthesis Metal , 26, 267 (1988). The compound of the present invention may optionally be doped with any desired dopant (for example, a halogen or a salt to be used in the above-mentioned polymerization step). As the catalyst to be used in the chemical oxidative polymerization method, there are mentioned, for example, chlorides such as ferric chloride or cupric chloride, sulfates such as ferric sulfate or cupric sulfate, metal oxides such as lead dioxide or manganese dioxide, peroxides such as potassium persulfate, ammonium persulfate or hydrogen peroxide, quinones such as benzoquinone, halogens such as iodine or bromine, as well as potassium ferricyanide.

The amount of the catalyst to be used in the reaction varies, depending upon the characteristic of the monomer compound and the catalyst to be used, but it may be within the range of from 0.01 to 10 as the molar ratio of catalyst/monomer compound. As the electrode material to be used in the electrolytic oxidative polymerization method, there are mentioned, for example, metal electrodes (e.g., Au, Pt, Ni, Cu, Sn, Zn, Ag, Ru, stainless steel), carbon electrodes (e.g., glassy carbon), and metal oxide containing electrodes (e.g, SnO₂, In₂O₃). It is preferred to employ additionally a reference electrode. As the solvent usable in the chemical oxidative polymerization method and the electrolytic oxidative polymerization method, there are mentioned, for example, organic solvents such as acetonitrile, dimethylsulfate, N,N-dimethylacetamide, N,N-dimethylformamide, dimethylsulfoxide, sulforan, formamide, dimethoxyethane, propylene carbonate, dioxane, methanol, ethanol, gamma-butyrolactone, nitrobenzene, tetrahydrofuran or nitromethane, or water or a mixture of them.

Where the dispersing agent is used, the amount of the dispersing agent may be from 1 to 300% by weight, preferably from 5 to 200% by weight, to the monomer. Where the surfactant is used, the amount thereof may be from 0.01 to 50% by weight, preferably from 0.1 to 20% by weight, to the monomer. The aqueous dispersion may be subjected to dialysis or ultra-filtration. The above-mentioned electroconductive compound may be added to the aqueous dispersion, or a high polymer compound such as polyvinyl acetate polymer may be blended therewith. The electron-conductive high polymer of the present invention may be combined with a solid polyelectrolyte to form a laminate, which may be used as an electroconductive material for a polymer battery. The laminate may have plural layers each made of the electron-conductive high polymer of the present invention. The laminate may also have plural layers made of the electron-conductive high polymer of the present invention and any other known electron-conductive high polymer. Additionally, the laminate may further have one or more constitutive layers containing salts of metal ions of Group Ia or Group IIa of the Periodic Table. In any case, however, it is preferred that the solid polyelectrolyte is kept in direct contact with the electron-conductive high polymer of the present invention in the constitution of the laminate. The solid polyelectrolyte to be used for forming the integrated(laminated) electroconductive material with the electron-conductive high polymer of the present invention may be a combination of a cation polymer, an anion polymer a polyacrylonitrile, a polyalkylene oxide polymer (e.g., PEO, PPO or PEO-containing silicon compounds or phosphagens), or a polyvinyl alcohol, and a salt. Specific examples of the substances are described in JP-A-61-256573, JP-A-61-124001, JP-A-62-20263, JP-A-62-139266, JP-A-63-241066, JP-A-63-241026, JP-A-63-135477, JP-A-63-142061, JP-A-63-130613, JP-A-60-23974, JP-A-63-136409, JP-A-63-193954, JP-A-63-186766 and JP-A-63-205364, and Macromolecules , Vol. 21, page 648. As examples of the salt of constituting the solid polyelectrolyte, the electroconductive salts which may be used in polymerization of the above-mentioned chemical oxidative polymerization method or electrolytic oxidative polymerization method may be referred to. Preferably, salts of metal ions of Group Ia or Group IIa of the Periodic Table are used. Especially preferred are Li salts. The integrated electroconductive material may be prepared as follows: Where the electron-conductive high polymer of the present invention is obtained by the chemical oxidation polymerization method as a powdery or bulky product, the product is shaped into a film by compression moulding and the resulting film may be stuck to a solid polyelectrolyte film under pressure to obtain the intended integrated electroconductive material. Where the electron-conductive high polymer of the present invention is obtained as an aqueous dispersion, it may be coated on a solid polyelectrolyte film by a known coating method, for example, by roller coating, spin coating, dip coating or spray coating method or by a known extrusion coating method, and the coated layer may be dried by a known drying method. Alternatively, a solid polyelectrolyte is dissolved or melted and the resulting solution or molten liquid may be applied to the electron-conductive high polymer film of the present invention as formed on an electrode by the electrolytic oxidative polymerization method or on the polymer film as filmed by the above-mentioned means, to thereby form a laminate structure film. The electron-conductive high polymer of the present invention may be used in combination with an organic solvent such as an alkali metal salt-containing propylene carbonate or gamma-butyrolactone. As the compound of the present invention has a function of a solid polyelectrolyte e.g., ion-conductive property, the electroconductive laminate material of the present invention may not have an electrolyte layer. For instance, only a separator may be provided between the positive pole (made of the compound of the present invention) and the negative pole, and the resulting laminate may function as a battery. For preparing the integrated material of the present invention, the constitutive components are previously separately prepared and then they are laminated; or alternatively, a positive pole material is first coated or applied to a separator and then a negative pole material may then be applied to the resulting integrated component. It is preferred that an organic solvent (for example, propylene carbonate, ethylene carbonate, gamma-butyrolactone, dimethoxyethane or methyltetrahydrofuran) is previously infiltrated into the separator to be used for the purpose, in order that the ion of the negative pole material (for example, Li⁺) may be diffused into the separator with ease. The organic solvent may contain a lithium salt. As the material for the separator, anyone of polyolefins, polyesters, vinyl chloride, fluoro-resins, polyamides, polysulfones, celluloses or polyurethanes may be used. The separator may be treated by plasma treating, glow treating, radiation treating, plasma polymerization treating, plasma-initiation polymerization treating, radiation polymerization treating or radiation-initiation polymerization treating. Next, specific examples of the compounds of the present invention as well as examples of preparation of the compounds are mentioned below.

Synthesis Example 1 : Production of Compound No. 1 of the Invention: 21.5 g of o-nitrophenethyl alcohol, 100 ml of acetonitrile and 11.7 g of pyridine were stirred with cooling under freezing point, whereupon 15.3 g of methacryloyl chloride was dropwise added thereto over a period of 30 minutes. After the whole was stirred for further one hour, 200 ml of ethyl acetate and 300 ml of water were added thereto, and the ethyl acetate layer was extracted out. This was washed with 300 ml of water, and an ethyl acetate solution containing o-nitrophenethyl methacrylate (1-A) was obtained. 50 g of reduced iron, 0.5 g of ammonium chloride, 30 ml of water, 200 ml of ethanol and 1 g of acetic acid were heated up to 75°C with stirring. The previously prepared ethyl acetate solution (1-A) was dropwise added to the resulting aqueous solution over a period of one hour and then the whole was stirred for further 3 hours. The insoluble substance in the reaction mixture was removed by filtration, and the resulting filtrate was concentrated and purified through silica gel column using chloroform as a developer solvent. As a result, 23 g of o-aminophenethyl methacrylate (1-B) was obtained.

Measurement of Electroconductivity of Laminate Material : Each plate prepared as above was combined with a cast film of a solid polyelectrolyte (thickness: about 200 microns) and the two were then sandwiched between stainless steel plates to prepare a laminate material. The electroconductivity of the thus prepared laminate material was measured (Cole-Cole plot method), and the results obtained are shown in Table 1 and Table A. Said Electrolyte Film : 1 g of CH₂=CH-COO(C₂H₄O)₉-CO-CH=CH₂, 6 g of propylene carbonate, 1.5 g of LiClO₄ and 10 mg of azoisobutyronitrile were dissolved in acetone, cast on a Teflon plate and then polymerized thereon at 80°C for 4 hours to form a solid polyelectrolyte film. (The electroconductivity of the film as obtained by Cole-Cole plot method was 3×10⁻³ S/cm².) Repeated Charge-Discharge Test 1 : A lithium sheet was attached to the laminate material obtained as above, under pressure, and put in a stainless steel case. The case was then sealed with an insulating synthetic rubber and shaped under compression to form a battery as shown in Fig. 1. The battery is a secondary battery, and this was subjected to a repeated charge-discharge test, where the average voltage after 100 cycles or 10 cycles was measured at 20°C and -25°C. The results obtained are shown in Table 1 and Table A. Repeated Charge-Discharge Test 2 : Each plate prepared as above was dipped in a 20% LiClO₄ acetonitrile-propylene carbonate solution (acetonitrile/propylene carbonate = 80/20) and then dried. This was laminated with a propylene carbonate-infiltrated separator (polypropylene) and a lithium sheet and the resulting laminate was put in a stainless steel case. Then the case was sealed with an insulating synthetic rubber and shaped under compression to prepare a battery as shown in Fig 2. The battery is a secondary battery, and this was subjected to a repeated charge-discharge test, where the average voltage after 10 cycles was measured at 20°C. The results obtained are shown in Table 2 below. Molecular Weight (Weight Average Molecular Weight) The molecular weight was obtained using gel-permeation chromatography (GPC).
