| Popis: | 97 In this present study, the polyaniline/MnOX electrodes were electroplated onto ITO using electrochemical deposition route, by which the deposition parameters for the specific capacitance. Influences of synthetic conditions on the characteristics of polyaniline/MnOX electrode were studied, including: the amount of aniline monomer and sulfuric Acid, the acid of different doping, the base, and the comparability of preparation composites by different electrochemical deposition route. The electrochemical characteristics of composites were studied by cyclic voltammetry (CV), the characteristics of polyaniline/MnOX composites were examined in terms of the FT-IR. The results show that the highest capacitance of polyaniline/MnOX composites was obtained, and prepared with pulsed electrochemical deposition from the electrolyte containing 0.1 M Aniline, 0.5 M sulfuric Acid, 0.1 M Manganese(II) Acetate, 0.5 M Sodium Acetate. The capacitance reaches 166.6 F/g. The specific capacitance decayed about 12.6 % after 1000 cycles scanning in the Na2SO4 electrolyte. It demonstrates that polyaniline/MnOX composites have a high stability. |
