Preparation and electrochemical properties of polyaniline nanofibers/graphene composite

以氧化石墨烯(GO)为基体,采用界面聚合法制备了聚苯胺纳米纤维/氧化石墨烯的复合物(PA-NI/GO),经水合肼还原和APS再氧化得到聚苯胺纳米纤维/石墨烯复合物(PANI/GR).用FT-IR、UV-Vis、XRD、SEM和TEM对复合物的结构和形貌进行表征,结果表明氧化石墨烯不仅为苯胺提供了聚合的基体,同时对聚苯胺有掺杂作用,聚苯胺纤维夹在片状石墨烯之间呈现“三明治”结构.通过循环伏安和恒流充放电测试发现,PANI/GR复合材料表现出双电层电容和法拉第赝电容双重特点,受协同效应的作用,在电流密度为400mA/g时,比容量高达460F/g,呈现出优异的电化学活性.
