Quartz Crystal Microbalance Studies: Solvent Effects in Conducting Polymer Films

Abstract

The stoichiometry and mechanism of the intercalation of incorporation of (1) solvent and (2) counterion during oxidation/reduction of electroactive polymer films can be established for some systems by the use of QCM techniques. Counterion motion may be predicted from coulometric charge data, and differences between these values and the actual mass change measured by QCM are accounted for, in simple cases, by solvent motion. Evaluation of electrolyte incorporation during 'break-in' of the films were also possible. Keywords: Polymeric films; Quartz crystal microbalances; Electrochemistry; Redox process.
