Abstract:Kinetic degradation process of PAn films during aniline polymerization was in situ monitored by UV-Visible absorption spectrum. The effects of anodic potential, acidity and monomer concentration on the degradation process were also investigated. The experiment results displayed that the more positive the anodic potential, the higher the acidity of the solution, the higher the concentration of aniline, the faster the PAn films degradation speed. Which was similar to the results obtained when the kinetic degradation process of PAn films was studied in blank solutions by cyclic voltammetry.
