Abstract
The degradation mechanisms in polyaniline (PANI) thin films polymerized on SnO2 after a large number of coloration/bleaching voltammetric cycles were investigated using optical and spectroscopic techniques, allowing us to follow the chemical changes related to the degradation. HCl solutions with different pH (0 and 3) were used and the role of the coloration potential was studied. The number and the nature of the polarons in the colored form play a leading part in the polymer stability, and they are modified by the cycling. This point was particularly emphasized here.
