Abstract
The redox mechanism of the conducting polymer film of poly-o-phenylenediamine (P-o-PD) in acid solution has been studied by cyclic voltammetry(CV), electrochemical insitu resonance Raman spectroscopy and UV-Vis subtractive reflectance spectroscopy, The results of the CV show that the redox process of P-o-PD is controlled by the surface processes and three steady redox states are formed in the redox process, The in-situ resonance Raman spectra not only verify the existence of the three steady states of P-o-PD, but also indicate that the structure of P-o-PD is dominated by a ladder polymer with phenazine rings, The three kinds of P-o-PD display different stabilities and UV-Vis aborption spectra, Furthermore, the in-situ time-resolved UV-Vis reflectance spectroscopy is used to study the dynamic redox process of P-o-PD, and a possible reaction mechanism is proposed at last.
