摘要: In this study, nano-polyanline and manganese oxide nanometer tubular composites (nano-PANI@MnO2) were prepared by a surface initiated polymerization method and used as electrochemical capacitor electrode materials; and the effect of aniline amount on the microstructure and electrochemical performance was investigated. The microstructures and surface morphologies of nano-PANI@MnO2 were characterized by X-ray diffraction, scanning electron microscopy and fourier transformation infrared spectroscope. The electrochemical performance of these composite materials was performed with cyclic voltammetry, charge-discharge test and electrochemical impedance spectroscopy, respectively. The results demonstrate that the feed ratio of aniline to MnO2 played a very important role in constructing the hierarchically nano-structure, which would, hence, determine the electrochemical performance of the materials. Using the templateassisted strategy and controlling the feed ratio of aniline to MnO2, the nanometer tubular structure of nano-PANI@MnO2 was obtained. A maximum specific capacitance of 386 F/g was achieved in aqueous 1 mol/L NaNO3 electrolyte with the potential range from 0 to 0.6 V (vs. SCE).
