采用简单的化学氧化聚合法,制备了分散性良好且尺寸均一的聚苯胺(PANI)纳米线电极材料,其直径和长度分别为~60nm和~1μm。三电极体系电化学测试结果表明PANI纳米线电极在电流密度为0.5A/g时的质量比电容为505F/g,电流密度从0.5A/g增至20A/g的电容保持率高达78%。PANI纳米线电极材料有望成为组装高倍率性能超级电容器的可选电极材料。
Polyaniline (PANI) nanowire electrode materials with good dispersion and uniform size were prepared by simple chemical oxidation polymerization method. Their diameter and length were ~ 60nm and ~ 1μm, respectively. The results of electrochemical tests showed that the mass specific capacitance of PANI nanowire electrode was 505F / g at a current density of 0.5A / g and the capacitance retention of 78% at a current density of 0.5A / g to 20A / g. PANI nanowire electrode materials are expected to become an optional electrode material for assembling high-rate performance supercapacitors.
