| Abstract: | Electroactive polyaniline(PANI) thin films were synthesized on platinum substrates by electrochemical polymerization,the electrochemical quartz crystal microbalance(EQCM) technique was adopted to investigate the polymerization process of the PANI film and its redox behavior in phenol solution.Combined with cyclic voltammetry(CV),electroactivity and stability of the PANI film cycled between the reduced,leucoemeraldine(L) state and the half-oxidized,emeraldine(E) state or between L and the fully oxidized,pemi... |
