摘要: 本文以活性中间相炭微球为基底,过硫酸铵(APS)为氧化剂,通过原位化学聚合法聚合苯胺,得到聚苯胺/活性中间相炭微球复合材料(PANI/A-MCMB),采用扫描电子显微镜(SEM)、X-射线衍射仪(XRD)对其形貌和结构进行表征。以PANI/A-MCMB复合物为电极活性物质,1.0 mol/L H2SO4水溶液为电解液,组装对称型超级电容器,用循环伏安法(CV)、电化学交流阻抗(EIS)、恒流充放电(GCD)等测试手段测试超级电容器的电化学性能。实验结果表明,电流密度恒为0.1 A/g时,PANI/A-MCMB复合材料单电极比容量为301.6 F/g,1 000次循环后比容量为276.3 F/g,比电容保持率为91.6%,较PANI材料(比容量为228 F/g,1 000次循环后比电容保持率为39.5%)具有更好的比容量和循环稳定性。

Abstract: In this paper, polyaniline/activated mesocarbon microbeads (PANI/A-MCMB) composite material was obtained through in-situ chemical polymerization of aniline by using activated mesocarbon microbeads (MCMB) as substrate and ammonium peroxydisulfate (APS) as oxidizing agent. The morphology and structure of prepared PANI/A-MCMB composite material was characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). A symmetric redox supercapacitor was assembled with PANI/A-MCMB composite as active electrode material and 1.0 mol/L H2SO4 aqueous solution as electrolyte, and the electrochemical properties of this PANI/A-MCMB supercapacitor were investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charge/ discharge tests. The experimental results show that the single specific capacitance of PANI/A-MCMB composite materials is 301.6 F/g at current density for 0.1 A/g, the specific capacitance is 276.3 F/g and the capacity retention is 91.6 % after 1 000 charge/discharge cycles. PANI/A-MCMB composite materials have higher specific capacity and better cyclic stability than PANI electrode materials whose single specific capacitance of PANI is only 228 F/g and the capacity retention is 39.5% after 1 000 charge/discharge cycles.
