不同氧化剂制备的聚苯胺电化学性能研究
Electrochemical performance of polyaniline prepared by different oxidizing agent
摘要
Abstract
Polyaniline was prepared by chemical in-situ polymerization at ambient temperature, using manganese dioxide or ammonium persulphate as oxidant. The morphology and structure of polyaniline were characterized by scanning electron microscopy(SEM), Fourier transform infrared spectroscopy(FTIR) and X-ray diffraction(XRD). The electrochemical performances of the supercapacitor assembled with polyaniline were investigated by cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge-discharge. These results show that the specific capacity of the M-PANI electrode prepared by manganese dioxide was about 260 F/g at the charge-discharge current density of 5 mA/cm~2. After 300 charge-discharge cycles the specific capacity of the M-PANI electrode was about 204 F/g. For comparison, M-PANI has better cycle performance and higher capacity than N-PANI, which was prepared by ammonium persulphate.关键词
