摘　　要：通过电化学沉积法制备得到聚苯胺/炭微球(PANI/CMS)复合电极材料,通过场发射扫描电子显微镜和红外光谱对PANI/CMS复合材料进行形貌和结构表征。并采用循环伏安、恒电流充放电、电化学阻抗谱及循环寿命测试等技术考察其电化学行为。结果表明:PANI均匀包覆于CMSs表面;在电流密度为1 A·g^(-1)时,复合材料的比电容达到206 F·g^(-1);PANI/CM S复合材料表现出优异的电化学稳定性。说明PANI/CMS复合材料有望作为电极材料用于超级电容器。A polyaniline-carbon microsphere（PANI-CMS） hybrid was prepared by an electrochemical deposition method and used as an electrode for supercapacitors.Field emission scanning electron microscopy and Fourier transform infra-red spectroscopy were used to characterize its morphology and structure.The supercapacitive performance of the hybrid was investigated by cyclic voltammetry,galvanostatic charge/discharge,electrochemical impedance spectroscopy and cycling tests.Results indicate that polyaniline is uniformly coated on the outer surfaces of the CMSs by the electrochemical deposition.The hybrid has a specific capacitance of 206 F·g^-1 at a current density of 1 A·g^-1.It has a higher specific capacitance and more stable cycle performance than PANI,which is ascribed to a synergistic effect between the PANI and the CMSs.
