DISPERSION OF ELECTRICALLY CONDUCTIVE POLYMER, AND ELECTRICALLY CONDUCTIVE POLYMER AND USE THEREOF

WIPO Patent Application WO/2013/035548

A1

[Problem] To provide: an electrically conductive polymer having high electrical conductivity and excellent heat resistance; and a solid electrolytic capacitor having low ESR and high reliability under high-temperature conditions and rarely undergoing current leakage, and an electrically conductive film having high electrical conductivity and excellent heat resistance, both of which are produced using the electrically conductive polymer. [Solution] A dispersion of an electrically conductive polymer is produced by the oxidative polymerization of a thiophene or a derivative thereof in water or an aqueous solution comprising a mixture of water and a water-miscible solvent in the presence of a copolymer of styrenesulfonic acid and at least one non-sulfonic-acid-type monomer selected from the group consisting of a methacrylic acid ester, an acrylic acid ester, an alkoxysilane compound containing an unsaturated hydrocarbon and hydrolysates thereof. A solid electrolytic capacitor is produced using the electrically conductive polymer as a solid electrolyte. An electrically conductive film comprises the electrically conductive polymer.
