| Abstract: | The degradation process of aniline on glassy carbon electrode during polymerization was investigated by electrochemistry and spectrum electrochemistry.Cyclic voltammograms showed four redox peaks within the potential limit of -0.2 to 1.0 V.The cyclic voltammetric curves of the PAn films in H 2SO 4 aqueous solution with/without containing PAP were compared,and the absorbance of the aniline electrolyte during polymerization was in situ measured by UV-Visible absorption spectrum.The results displayed the existence of PAP,which was the degradation product of the PAn films.The kinetic degradation process of aniline during polymerization was also in situ preliminarily investigated by UV-Visible absorption spectrum. |
