纳米线型导电聚合物是一种具有良好应用前景的超级电容器电极材料,该文用简易的原位化学氧化法制备了微孔炭/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考察了其电化学电容性能,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。
Nanowire conductive polymer is a kind of supercapacitor electrode material with good application prospect. In this paper, MC / PANI nanocomposites were prepared by a simple in-situ chemical oxidation method The electrochemical properties of the composite electrode were investigated by cyclic voltammetry, AC impedance and constant current charge-discharge technique in 1 mol / L H2SO4. The results showed that under the current density of 0.2 A / g , The initial charge-discharge specific capacitance of MC / PANI electrode can reach 329 F / g, higher than that of PANI electrode at 259 F / g, and MC / PANI electrode charge transfer resistance (Rct) is smaller than that of MC and PANI Electrochemical properties of electrode materials.
