Quartz Crystal Microbalance Analysis: Partial Cation Release During Oxidation of Conducting Polymers
Abstract
In the process of charging (or oxidizing) conducting polymers, e.g., polypyrrole, polythiophene, polyaniline, it has been common to assume that exclusively anions can compensate the excess charge of the radical cation sites of polypyrrole in the oxidized state. Very recently, however, cation insertion has also been indicated by some workers (1-8). In this short note, the authors report strong evidence of cation/release in polypyrrole film and the dependence of the proportion of anion and cation charge compensation of film thickness during the oxidation process. Keywords: Crystal microbalance, Conducting polymers, Redox polymers.
