✦ Synopsis

The degradation of polyaniline at anodic potentials was studied with in situ UV-Vis spectroscopy of polymer-coated ITO glass electrodes. Spectral changes at high potential values were observed and discussed. Degradation follows first-order kinetics, with rate constants ranging from 8.40 ϫ 10 Ϫ6 to 2.93 ϫ 10 Ϫ3 s Ϫ1 at electrode potentials of E NHE ϭ ϩ0.85 to ϩ1.20 V.
