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。 The montmorillonite / polypyrrole (MMT / PPy) was prepared by gas-liquid phase polymerization of the resulting suspension with pyrrole (Py) using FeCl3 as oxidant and sodium montmorillonite (MMT) Composites. The results of XRD, FTIR and SEM showed that Py monomer polymerized in the lamellae of MMT, and the interlayer spacing of MMT increased with the increase of PPy content. The MMT / PPy composites show the infrared characteristic absorption peaks of MMT and PPy, but some absorption peaks appear blue shift. SEM observation showed that MMT / PPy showed flaky morphological features. When MMT was removed, PPy was still flaky, which was different from that of pure PPy. Conductivity tests showed that the conductivity of MMT / PPy composites increased with the increase of PPy content. When the content of PPy was 40.9 wt%, the conductivity of MMT / PPy reached the conductivity of PPy (10-1S / cm) The MMT / PPy conductivity of 54.3 wt% PPy is even slightly higher than PPy.
