摘要:

：纳米线型导电聚合物是一种具有良好应用前景的电容器电极材料，本论文中，用简易的原位化学氧化法制备了微孔碳/聚苯胺纳米线(MC/PANI)复合材料，并以此复合材料为活性物质制备工作电极，在1 mol/L H2SO4中，通过循环伏安、交流阻抗和恒流充放电技术研究了其电化学电容性能，研究结果表明：在0.2 A/g的电流密度下，MC/PANI电极首次充放电比电容可达到329 F/g， 高于PANI电极的259 F/g，且MC/PANI电极电荷传递电阻（Rct）小于MC和PANI，可见纳米线型PANI可加强电极材料的电化学性能。

Abstract:

Conduction polymer nanowires arrays have promising applications in supercapacitor electrode materials. In this paper, It reported a facial approach to synthesize microporous carbon-polyaniline nanowire (MC/PANI) composites, the working electrode was prepared with the MC/PANI composites, and the electrochemical capacitance of it were characterized by cyclic voltammetry, A.C. impedance and galvanostatic charge-discharge in 1 mol/L H2SO4 solution, The result indicated that specific capacitance of the MC/PANI electrode can be high as 329 F/g at a current density of 0.2 A/g, which is higher than 259 F/g of PANI electrode at the same condition, the charge transfer resistance(Rct) of MC/PANI is smaller than MC or PANI. therefore, it is demonstrated that the PANI nanowires could enhance the electrochemical performance of electrode materials.
