中文摘要：

采用化学法在氧化石墨烯（GO）表面垂直生长出聚苯胺（PANI）纳米线阵列。利用SEM、FT-IR、Raman对所制备的GO／PANI复合材料的形貌及结构进行表征。该复合材料的电化学电容性能通过循环伏安（CV）、交流阻抗（EIS）和恒流充放电进行表征。研究结果表明：在0．2A／g的电流密度下，GO／PANI电极首次充放电比电容可高达469F／g，高于纯PANI电极的452F／g，复合材料的电荷传递电阻为1Ω·cm^2。同时，GO／PANI的循环稳定性及倍率特性得到极大的增强。

英文摘要：

We introduced a facile chemical polymerization method to construct nanocomposites by combining conduc-ting polyaniline （PANI） nanowires arrays with graphene oxide （GO） nanosheets. The surface morphology and structure of nanocomposites are characterized by SEM, FT-IR, Raman measurements. Electrochemical properties were character-ized by cyclic voltammetry（CV）, electrochemical impedance spectroscopy （EIS） and gaivanostatic charge/discharge. The results indicated that the average specific capacitance of nanocomposites could be as high as 469 F/g in the potential range from 0 to 0. 7V at a current density of 0. 2 A/g, higher than pure PANI electrode （452 F/g）, showing a synergistic of PANI and GO. The charge transfer resistance （Rct） of GO/PANI was 1 Ω· cm^2. They also exhibited greatly to improve electrochemical stability and rate performances.
