CONDUCTIVE POLYMER SUSPENSION AND METHOD FOR PRODUCING THE SAME, CONDUCTIVE POLYMER MATERIAL, AND SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a conductive polymer suspension for providing a conductive polymer material having high conductivity and a method for producing the same, and to particularly provide a solid electrolytic capacitor having low ESR and a method for producing the same. SOLUTION: In an emulsion formed by emulsifying a monomer providing a conductive polymer in a water solution comprising a dopant of a low molecular organic acid or a salt thereof using a nonionic surfactant, the monomer is subjected to chemical oxidative polymerization using an oxidizing agent to synthesize the conductive polymer. The obtained conductive polymer is purified, and then, the purified conductive polymer and an oxidizing agent are mixed in an aqueous solvent containing a polyacid component to produce the conductive polymer suspension.
