Electrochemical Polymerization of Polyaniline Doped with Mn2+ as Electrode Material for Electrochemical Supercapacitors

Keywords： polyaniline , Mn2 + , electro-activity , specific capacitance

在硫酸介质中以苯胺和MnSO4ˉH2O为单体,采用循环伏安法(CV)合成了Mn2+掺杂的聚苯胺(PANI).利用红外光谱、X射线衍射、场发射扫描电镜等手段对其结构和形貌进行了表征.在0.5 mol/L H2SO4电解液中,对合成的粉末构成的电极进行了循环伏安、恒流充放电(CP)及交流阻抗(EIS)等电化学性能测试.结果表明,电化学合成Mn2+掺杂的PANI有良好的电化学电容性,以5mA/cM的电流密度放电时比电容高达859 F/g,循环500次后比电容保持在540F/g,是一种具有优良应用前景的超级电容器材料.
