中文摘要：

以具有高比表面积的活性中间相活性碳微球（a-MCMB）、苯胺（ANI）为主要原料,过硫酸铵为氧化剂,通过原位化学聚合法在a-MCMB表面沉积聚苯胺（PANI）,首次制得纳米PANI/a-MCMB新型复合材料,通过XRD、SEM对样品的晶型结构和表面形貌进行表征,并将得到的复合材料组装成超级电容器,用循环伏安、交流阻抗、恒流充放电以及循环性能测试技术对该材料进行电化学测试。结果显示,在1MH2SO4溶液中,复合材料的比容量达到288.46F/g。

英文摘要：

For the first time,polyaniline /activity mesophase carbon microbeads composite was synthesized by in-situ chemical polymerization which used ammonium persulfate（APS） as oxidant,the middle-phase activated carbon microspheres and aniline（ANI） as the main raw material.The microstructure and component of the obtained materials were characterized by scanning electron microscope（SEM） and X-ray diffraction（XRD）.With the aim to investigate the electrochemical performances of the composite,Hybrid capacitor was fabricated,and cyclic voltammetry,ac impedance spectroscopy,galvanostatic charge-discharge tests were done.The results show that in 1M H2SO4 aqueous solution as electrolyte,specific capacitance of composite materials increases to 288.46F/g.
