SIMULTANEOUS ALTERNATING-CURRENT IMPEDANCE ELECTRON-SPIN RESONANCE STUDY OF ELECTROCHEMICAL DOPING IN POLYPYRROLE

Abstract:

The electrochemical doping of polypyrrole has been studied using simultaneous a.c. impedance and in-situ electrochemical e.s.r. measurements. A quantitative estimate of the polypyrrole conductivity as a function of doping level has been obtained and the corresponding change in the polaron concentration measured by in-situ electrochemical e.s.r. It was found that at low doping levels there was a good correlation between these two properties. It is suggested that the polaron may be responsible ...
