摘要: 通过化学氧化法合成了盐酸掺杂的聚苯胺( PNAI) ，然后采用X 射线衍射( XＲD) 和紫外－可见光谱( UV －Vis) 对聚苯胺进行了表征，并且用循环伏安( CV) 、交流阻抗( EIS) 及恒流充放电测试研究了不同导电剂对聚苯胺电极超级电容器性能的影响．结果表明: 在1 mol /L H2 SO4电解液中，电流密度为0． 6 A/g 时，以鳞片石墨，乙炔黑，SUPEＲ P LI 导电炭黑与KS6 石墨的比分别为1∶ 1． 5，1∶ 1，1． 5∶ 1 为导电剂时，聚苯胺的比电容分别为126，214，166，220 和 269 F /g．Study on the effect of conductive material on the performance of polyaniline supercapacitor WANG Li-li，XING Ｒui-guang ( Ｒare Earth School ，Inner Mongolia University of Science and Technology，Baotou 014010，China)
