中文摘要：

采用恒电流法在不同浓度的苯胺与1mol·L^-1高氯酸的混合溶液中,在氧化铟锡（ITO）导电玻璃基底上制备了聚苯胺纳米线.系统研究了苯胺浓度、合成时间对其形貌及电化学性能的影响.SEM结果显示,在不同条件下制得的聚苯胺为线状,直径大约在100～500nm.采用恒电流充放电、循环伏安和交流阻抗谱对聚苯胺纳米线电极的电化学性能进行了表征.结果表明,其在3mol·L^-1NH4Cl和2mol·L^-1ZnCl2的混合溶液中恒电流充放电（电压范围-0.2～0.5V）的比容量最高可达746.7F·g^-1.

英文摘要：

Polyaniline（PANI）nanowires on indium tin oxides（ITO）conducting glass substrates were synthesized by means of a galvanostatic method from an aqueous solution of 1.0 mol·L^-1 HClO4 and different concentrations of aniline monomer.The effects of aniline concentration and synthesis time on their morphology and electrochemical performance were systematically investigated.Scanning electron microscopy（SEM）revealed that PANI synthesized in different conditions was a wire in shape with different diameters of 100 to 500 nm.Electrochemical characterization of the PANI electrode was performed in an aqueous solution of 3 mol·L^-1 NH4Cl and 2 mol·L^-1 ZnCl2 by galvanostatic charge-discharge,cyclic voltammetry（CV）and electrochemical impedance spectroscopy（EIS）.A high specific capacitance of 746.7 F·g^-1 was obtained within the potential range of-0.2 to 0.5 V.
