Preparation and capacitive property of polyaniline/SnO_2/graphene oxide nanocomposite |
| |
| Abstract: | The polyaniline/SnO2/graphene oxide(PANI/SnO2/GO) composite was synthesized by a simple process.The structure and morphology of as-synthesized products were characterized by X-ray diffractometer,transmission electron microscopy,fourier transform infrared spectrograph and thermogravimetric analyzer.The electrochemical and capacitive properties were studied by cyclic voltammetry,nyquist plot and charge/discharge test.The electrochemical measurement results show that the PANI/SnO2/GO composite has a high specific capacitance and long cycle life(over 1 000 times). |
