ELECTROCONDUCTIVE POLYMER SOLUTION AND METHOD FOR PRODUCING THE SAME, ELECTROCONDUCTIVE POLYMER MATERIAL, AND SOLID ELECTROLYTIC CAPACITOR USING THE SAME AND METHOD FOR PRODUCING THE SAME

摘要

Provided are an electroconductive polymer solution in which the carbon material has excellent dispersibility, an electroconductive polymer material which has a high electroconductivity and which can be produced by a simple method, and a solid electrolytic capacitor and a method for producing the same which has a low ESR without increasing a leakage current. An electroconductive polymer solution according to an exemplary embodiment of the invention contains an electroconductive polymer, a polysulfonic acid or a salt thereof which functions as a dopant to the electroconductive polymer, a mixture of a polyacid and a carbon material, and a solvent.
