以FeCl3为氧化剂,与钠基蒙脱土(MMT)以不同比例进行离子交换后所得悬浮液与吡咯(Py)单体进行气液相聚合,制备出蒙脱土/聚吡咯(MMT/PPy)复合材料.XRD、FTIR和SEM分析表明,Py单体在MMT的片层间发生了聚合反应,MMT的层间距随PPy含量增加不断变大.MMT/PPy复合材料呈现出MMT和PPy的红外特征吸收峰,但某些吸收峰出现蓝移.SEM观察显示MMT/PPy呈片状形态特征.当其中的MMT去除后,PPy仍为片状结构,与纯PPy的球粒形貌不同.电导率测试表明,MMT/PPy复合材料的电导率随PPy含量增加而提高,至40.9 wt%PPy含量时,MMT/PPy的电导率已达到PPy的电导率水平(10-1S/cm),含54.3 wt%PPy的MMT/PPy电导率甚至略高于PPy.
