Electrochemical Behavior of Polypyrrole Deposited on Nafion-coated Electrodes

Abstract

Abstract Anodic polymerization of pyrrole at Nafion-coated ITO or Au electrodes gives a polypyrrole-Nafion co-polymer film at the Nafion/electrode substrate interface. Sulfonate groups of Nafion and not the electrolyte anions are involved in the polymerization process. The redox reaction of the resulting polymer film occurs more easily than that of polypyrrole films prepared on the naked electrode substrate.
