Conductive polymer composition, solid electrolyte and solid electrolyte capacitor using the conductive polymer

Abstract

An electroconductive high molecule compound contains electroconductive high molecules, polyanion and ether compounds. The electroconductive high molecules are polypyrrole and derivates thereof, polythiophene and derivates thereof, polyaniline and derivates thereof, polyacetaldehyde and derivates thereof, poly(1, 2-ethenylidene thiofuran) and derivates thereof, poly(vinyl carbazole) and derivates thereof, and the copolymer of all the compounds. The formula of the ether compounds is shown as formula I, R2-(O-R1)n-R3 (in the formula I, at least one of R2 or R3 is one of ethylene, vinyl ether, acrylamide, acrylic acid, vinyl alcohol and alcohols that can all be replaced arbitrarily, and n is an integer between 1 and 20). In the solid electrolyte layers of a solid electrolytic capacitor, at least one layer contains electroconductive high molecules, polyanion and ether compound that has one functional group of ethylene, vinyl ether, acrylamide, acrylic acid, vinyl alcohol and alcohols that can all be replaced arbitrarily. Therefore, the capacitor has excellent electric volumetric properties and high temperature stability.
