摘要: 以介孔碳纳米线为基体, 通过电化学方法制备了新型聚苯胺/介孔碳纳米线(PANI/MCFs)复合材料, 采用SEM和TEM等手段对样品的结构和形貌进行了表征. 结果表明, 聚苯胺均匀附在介孔碳纳米线表面, 并填充到纳米线介孔孔道中. 将复合材料组装成三电极体系超级电容器, 用循环伏安、 恒流充放电和交流阻抗等方法对材料的电化学性能进行了测试. 结果显示, 在1 mol/L H2SO4溶液中, 复合材料的比电容达到391 F/g, 其循环稳定性也得到显著提高.

Abstract: A composite material was prepared through the electrochemical polymerization of aniline in the pores or on the surface of mesoporous carbon nanofibers by an electrochemical polymerization method. The surface morphology and structure of the composite material were characterized by scanning electron microscope(SEM) and transmission electron microscope(TEM). The supercapacitance performance of the composite material was investigated by cyclic voltammetry(CV), galvanostatic charge-discharge and Nyquist impedance test with a three-electrode system in 1 mol/L H2SO4 solution. The specific capacitance of the composite material is as high as 391 F/g at a current density of 0.5 A/g in the potential range of -0.2-0.8 V. The cycling stability is much better than that of pure polyaniline.

Key words: Supercapacitor, Mesoporous carbon nanofibers, Polyaniline, Composite electrode material
