Evaluation of Ion Intercalation in Conducting Polymers

Abstract

Redox(polyvinlyferrocene) and conducting polymer films(poly-3-methylthiophene and polypyrrole) films have been shown to insert anions and/or cations reversibly during redox cycling in order to maintain charge neutrality. Ionic motions across these polymer films have been attempted with the use of 2 techniques, viz., (1) cyclic voltammetric measurements of effects of electrolyte concentration on shifts in E(peak) based on the Nerst equation and (2) Quartz Crystal Microbalance Gravimetry. Keywords: Intercalation.
