Abstract

The temperature dependence of the electroactive polymer film voltammetric response is considered under conditions of surface or thin-layer behavior. Existing theory is used to show how Information regarding the variation of the electrode process with temperature and the transition between thin-layer and diffusion behavior can be obtained from experimental data. Poly(vinylferrocene) (PVF) and tetracyanoqulnodl-methane (TCNQ) polymer modified electrodes have been studied under the following conditions: PVF/CH3CN/0.1 M (C2H5)4NClO4, −30 to 50 °C; and TCNQ/aqueous pH 7 buffer, 2.5 to 55 °C. For the PVF electrodes the interaction parameter extracted from the wave shape of the surface voltammograms decreased markedly at the lower temperatures. For both systems it is suggested that the temperature dependence of the voltammetric response is strongly influenced by solvent swelling of the polymer film.
