摘要：
Polyaniline (PANI), acts as an electric insulator in the potential region greater than 0.7 V vs. Ag/AgCl. Even in the electroinactive potential region, the redox current of dissolved p-dimethoxybenzene was evident on a PANI film-modified electrode because p-dimethoxybenzene selectively permeates through the PANI film to reach the electrode substrate. For the electro-oxidation of the dissolved p-dimethoxybenzene, analyses of the rotating disk electrode (RDE) voltammograms using a PANI-modified RDE and steady-state current-potential curves using a PANI pellet electrode revealed that p-dimethoxybenzene was concentrated in the PANI during the electro-oxidation. Furthermore, the concentration increased the electric conductivity of PANI. (C) The Electrochemical Society of Japan, All rights reserved.
