In-situ cyclic voltammetry and cyclic resistometry analyses of conducting electroactive polymer membranes

Abstract

Organic conducting polymers are usually used as electrode deposited film, powder or free standing films. The electrochemical properties (e.g. electroactivity) of conducting polymers are usually studied as very thin deposited films (thickness<1micron). In this research, a special cell design was employed for simultaneous characterization of electroactivity and resistometry of the conducting electroactive polymers prepared as free standing film or membrane. PPy membranes doped with some benzene sulfonates were synthesized electrochemically, then the electrical conductivity and electroactivity of the films was measured after synthesized.
