摘要：

There is a significant accumulation of solution species in the film in all solution compositions and in the whole potential range studied. In 10 mol dm-3 HClO4 or H2SO4 solutions the films become highly swollen, which eventually leads to the dissolution of the films. Significant mass changes during the oxidation of the leucoemeraldine to emeraldine form can be observed only in the pH interval between pH 1 and 3, where the reduced poly(aniline) is practically unprotonated, while the half-oxidized material is protonated.
