英文摘要	以P123为模板剂,软模板法制备出纳米MnO2.酸性条件下引入苯胺并聚合,得到了MnO2/聚苯胺复合材料.X射线衍射(XRD)、红外光谱(IR),扫描电子显微镜(SEM)表征观察样品的结构、形貌.循环伏安、交流阻抗、恒电流充放电等测试MnO2/聚苯胺电极的电化学性能.结果表明:引入苯胺改变了样品纳米MnO2的形貌.MnO2/聚苯胺电极比容量高达190.8F·g-1,500次循环电极比容量仅衰减4.7%,库仑效率均保持在97%以上.; Nano-MnO2 was prepared by using P123 as a soft template.The MnO2 /polyaniline composite was further prepared by polymerization of aniline with the nano-MnO2 in acidic conditions and was investigated by XRD and IR.The morphology of nano-MnO2 observed by SEM was changed with the introduction of aniline.The electrochemical properties of MnO2 /PANI electrode were investigated using cyclic voltammetry,galvanostatic charge-discharge and electrochemical impedance spectroscopy.The specific capacitance of MnO2 /PANI electrode could reach as high as 190.8 F·g-1,which decayed only 4.7% over 500 cycles.And the coulombic efficiency has been maintained at above 97%.; 作者联系地址：中南大学化学化工学院;; Author's Address: College of Chemistry and Chemical engineering,Central South University,Changsha 410083,Hunan,China
