摘要
A selective permeability of the poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) films being prepared by electropolymerization of 2,6-dimethylphenol to the various redox species dissolved in the solution was investigated by means of hydrodynamic voltammetry at a rotating disk electrode. The selective permeability was found to be different for the PPO films prepared from the different electrolytic solutions. The PPO films, prepared from the basic methanolic solution, had a high selective permeability to hydrogen ion, but blocked the access of larger redox ions such as Fe(CN)//6**3** minus , Fe**2** plus , and (ethylenediaminetetraacetato)iron(III) (Fe(edta)** minus ) to the electrode surface.
