摘要
Studies have been conducted to further characterize over-oxidized polypyrrole films grown on carbon electrodes. Differences in apparent diffusion coefficients for various probes are interpreted via a model based on both hydrophobic and electrostatic interactions between the probe and polymer film. These electrode coatings are also compared to Nafion films, and the results of this study are discussed in terms of important considerations for the design of permselective electrodes.
