Title:
PROCESS FOR PRODUCING HIGH-STRENGTH POLYPYRROLE FILM
Document Type and Number:
WIPO Patent Application WO/2004/050748
Kind Code:
A1
Abstract:
A process for polypyrrole film production which comprises subjecting one or more monomers comprising pyrrole and/or a pyrrole derivative to electrolytic polymerization to form a pyrrole layer on a work electrode and peeling off the polypyrrole layer to obtain a polypyrrole film, wherein the electrolytic polymerization is conducted in an electrolytic solution containing an organic compound containing at least one bond or functional group selected among an ether bond, ester bond, carbonate bond, hydroxy, nitro, sulfo, and nitrile and/or a halogenated hydrocarbon as a solvent and the electrolytic solution contains ions of trifluoromethanesulfonic acid and/or anions containing two or more fluorine atoms per central atom, the working electrode being a metal electrode. The polypyrrole film obtained by the process can stably retain conductivity in the presence of oxygen and has excellent mechanical strength.
