| Abstract: | The electrochemical synthesis of polyaniline and poly(vinyl alcohol)(PANI/PVA) composite film on nickel substrate coated with PVA film was reported.The electrochromic properties of the composite film coated on ITO conductive plastics were studied.The process optimization of the electrochemical preparation of PANI/PVA composite film was discussed through cyclic voltammetry and A C impedance tests.Results indicated that the highest electrical activity of the composite film was achieved when the mol ratio of SSA to H2SO4 was 1:1,the excitation voltage ranged from 1.10 V to 1.15 V and the working voltage ranged from-0.2 V to 0.8 V with scanning 20 cycles.Compared with the PANI film prepared directly on ITO conductive plastics,the PANI/PVA composite film showed better electrochromic properties. |
