以三氯化铁(FeCl3)为氧化剂,对甲苯磺酸钠(TSANa)为掺杂剂,使进入经有机插层剂改性的有机蒙脱土(OMMT)层间的吡咯(Py)发生氧化聚合反应,制备了具有良好导电性的聚吡咯/有机蒙脱土(PPy/OMMT)纳米复合材料。结果表明,采用插层剂为十八烷基三甲基氯化铵(OTAC)改性的有机蒙脱土OMMT-O,FeCl3与Py的摩尔比为2 14,Py与OMMT-O的质量比为0 24,TSANa的浓度为0 023g·ml-1,在20℃反应6h,得到的PPy/OMMT-O纳米复合材料的电导率达到3 07S·cm-1。XRD测试表明,在形成复合材料过程中PPy已经插层进入到蒙脱土的片层中。
Ferric chloride (FeCl3) was used as an oxidant and sodium p-toluenesulfonate (TSANa) as a dopant to oxidize the pyrrole (Py) into the organic intercalated organo-montmorillonite (OMMT) The PPy / OMMT nanocomposites with good conductivity were prepared by polymerization. The results showed that the molar ratio of FeCl3 to Py was 21 with OMMT-O modified with octadecyltrimethylammonium chloride (OTAC), the mass ratio of Py to OMMT-O The results showed that the conductivity of PPy / OMMT-O nanocomposites reached 377S · cm-1 when the concentration of TSANa was 0 023g · ml-1 and reacted at 20 ℃ for 6h. XRD tests showed that PPy had intercalated into the montmorillonite layer during the formation of the composites.
