Preparation of polypyrroles, and films obtained by this method

摘要

Polypyrroles are prepared by electrochemical polymerization, in particular anodic oxidation, of pyrrole alone or together with comonomers, in an aqueous electrolyte solvent which consists of not less than 50% by weight of water, in the presence of aromatic sulfonic acids and/or their salts as conductive salts. The process gives polypyrrole films which have good mechanical properties and high electrical conductivities.
