Abstract
By the selective use of a homogeneous stable precursor solution in which no polymerization reactions immediately occur and which contains aromatic compounds such as pyrrole, thiophene, aromatic amines or their derivatives, oxidizing agents, and solvents, as a precursor solution of conductive polymer film, a homogeneous and tough conductive polymer film can be obtained when the said precursor solution is cast on a substrate and the solvents are evaporated to remove.
