There is no particular problem as long as it is a porous crosslinked polymer with continuous voids. Specific examples include urethane sponges, silicone sponges, and poval sponges. The desired shape can be obtained by cutting out the original sheet or block shape. This product is hereinafter referred to as a porous crosslinked polymer molded product. The mechanical properties of the composite of this material with polypyrrole mainly depend on the porous crosslinked polymer. From this fact, by using various porous crosslinked polymer moldings, it is possible to create conductive porous composites with various mechanical properties.

な複合化について述べる。The composite of the porous crosslinked polymer molded body and polypyrrole is performed by synthesizing polypyrrole in the porous crosslinked polymer molded body. Known methods for synthesizing polypyrrole include chemical oxidative polymerization and electrolytic oxidative polymerization of the monomer pyrrole. Hereinafter, specific conjugation will be described focusing on each polymerization method.

。A method of compounding by chemical oxidative polymerization is already known (Japanese Unexamined Patent Publication No. 61-123637). However, this method uses a thermoplastic polymer rather than a porous support, and its disadvantages include that it takes time for the seven polymers to impregnate and polymerize, and that it tends to become non-uniform in the thickness direction.
本発明では、下記に示す方法で上記の問題点を解決する

ロールは、細かな粒子状であることを特徴とする。The organic solvent for the virol solution may be one that does not dissolve the oxidizing agent but dissolves virol. Specifically, most organic solvents can be used, such as toluene, octane, isooctane, hexane, ethyl ether, petroleum ether, acetonitrile, chloroform, and monochloromethane, but considering the next process to remove the solvent, those with a low boiling point can be used. is desirable. Further, it is necessary that the porous crosslinked polymer molded body serving as the support is not dissolved or altered in quality. Since the oxidizing agent supported on the porous crosslinked polymer molded body cannot flow out into the solution, the oxidative polymerization of the five-membered heterocyclic compound occurs selectively only on the crosslinked polymer.
There is almost no wasted monomer. The polypyrrole obtained by this method is characterized by being in the form of fine particles.

られる。A composite method using electrolytic oxidation polymerization is already known (Japanese Unexamined Patent Publication No. 6O-177507), in which a thermoplastic film is formed on the anode, and a conductive polymer is electrolytically synthesized in the film. However, at this time, the monomer and supporting electrolyte must diffuse through the polymer film swollen with the solvent in the electrolyte solution to reach the anode surface. Combinations of electrolytes and polymer films that meet this condition are actually limited, and it is difficult to freely select a polymer film, and the formation rate of conductive polymer is slow, resulting in differences in conductivity in the thickness direction. The problem is that it is easy to use.
本発明者は、熱可塑性フィルムの代わりに多孔質架橋ポ

At this time, care must be taken to prevent the electrolyte from leaking from the interface between the electrode and the molded body. That is, the electrolytic solution and the anode surface are brought into contact through the pores of the molded body.

As shown in these figures, the electrical resistance of the electrically conductive porous composite of the present invention changes significantly with pressure. As pressure is applied, the electrical resistance first decreases greatly, then gradually decreases, and finally decreases linearly with the pressure.
