PANI-CNTs复合材料的制备及其在对称型全固态超级电容器中的应用

论文摘要

超级电容器寿命长、安全性高,并可以实现快速充放电,是化学电源研究的热点之一。文章通过简单的化学原位聚合法将聚苯胺(polyaniline,PANI)与碳纳米管(carbon nanotubes,CNTs)进行复合,得到聚苯胺纳米管(PANI-CNTs)复合材料。利用场发射扫描电子显微镜(field emission scanning electron microscope, FESEM)对其形貌和结构进行表征。循环伏安(cyclic voltammetry,CV)曲线、恒电流充放电(galvanostatic charge-discharge, GCD)曲线和循环寿命测试结果表明,纳米复合电极材料在三电极体系中,电流密度为1 A/g时,比电容高达690 F/g,3 000次循环后仍保持初始电容80%,在组装成柔性器件后,保留了优异的电化学性能,并展现出卓越的柔性机械性能。
