Abstract

Abstract: The redox electric charges of polyaniline synthesized by potentiostatic electrolysis in varius acids were mearsured,they were much higher than that of polyaniline synthesized by chemical method.The redox peaks of polyaniline synthesized at high anodic potential are decreased markedly.It might be caused by an irreversible degradation of polyaniline and/or a certain type of destruction of the polymer structure.A.C.impedance measurements at different potential show that the resistance of the polyaniline electrode varies with the electrode potential.

Key words: Electrochemical synthesis, Polyaniline, Powder electrode, Alternating current impedance
