METHOD FOR MANUFACTURING CONDUCTIVE POLYMER FINE-PARTICLE DISPERSOID, AND METHOD FOR MANUFACTURING ELECTROLYTIC CAPACITOR USING CONDUCTIVE POLYMER FINE-PARTICLE DISPERSOID

摘要

PROBLEM TO BE SOLVED: To reduce ESR of an electrolytic capacitor.;SOLUTION: A method for manufacturing a conductive polymer fine-particle dispersoid includes preparing a fluid dispersion containing a monomer having a π-conjugated structure, polyanion, and a solvent. The polyanion when the monomer is then subjected to oxidation polymerization contains at least one of polystyrene sulfonate and a salt thereof in which the color tone of a solution obtained by dissolving the polyanion in water so as to have a concentration of 2% is not less than 10 nor more than 1000 in Hazen color number measured by APHA method.;COPYRIGHT: (C)2015,JPO&INPIT
