中文摘要：

用化学氧化聚合法制得了草酸掺杂聚苯胺（H2C2O4-PANI）和柠檬酸掺杂聚苯胺（C6H8O7-PANI）,并与盐酸掺杂聚苯胺（HCl-PANI）做了对比研究。用红外光谱（FT-IR）、X射线衍射（XRD）和透射电镜（TEM）对掺杂聚苯胺的结构和形貌进行了表征。用循环伏安,恒流充放电和交流阻抗测试对材料在1 mol/L HCl溶液中的电化学电容行为进行了研究。结果表明：3种酸掺杂的聚苯胺具有不同的空间结构,电化学性能也有差异。与盐酸和柠檬酸掺杂的聚苯胺相比,草酸掺杂制备的聚苯胺表现出更优良的电化学电容行为,单电极比电容可达670 F/g。

英文摘要：

Two kinds of doped polyaniline （H2C2O4-PANI and C6H8Or-PANI） were synthesized by the chemical in-suit oxidation/polymeration and were studied by comparing with hydrochloride doped polyaniline （HC1-PANI）. The structure and morphology of the doped PANI materials were characterized by the FT-IR, XRD and TEM. The cyclic voltammetry, galvanostatic charge/discharge and AC impedance mea- surements were also used to investigate the electrochemical properties of doped PANI in 1 mol/L HCl electrolyte. The results suggest that different doped polyaniline have extended chain conformations and electrochemical performances. Compared with the polyaniline synthesized by the other two acids, PANI doped with H2C2O4 exhibits more outstanding electrochemical capacitor behavior with the specific capacitance of 670 F/g.
