摘要：

A new method for modifying polypyrrole films is described. It involves complete oxidation of the film. The film produced is electronically non-conductive but ionically conductive, and has ion-selective properties based on the exclusion of anionic species. The effective pH within the film can be controlled by the choice of supporting electrolyte used during the oxidative treatment, without loss of selectivity. Cyclic voltammetry is used to demonstrate the effect of film pH on the rate of dopamine oxidation in a neutral supporting electrolyte.
