In this work, we synthesized poly(methyl methacrylate) (PMMA)/expanded graphite (EG) nanocomposites by a new polymerization method. The volume electrical conductivity of the nanocomposite prepared by this way is very high (when the content of EG is about 8 wt %, the conductivity could reach 60 S/cm). The structure of the nanocomposite was investigated by SEM, TEM, IR, and XRD. And we found temperature and voltage were important parameters of governing the electrical conductivity of PMMA/EG nanocomposites. © 2006 Wiley Periodicals, Inc.

聚（甲基丙烯酸甲酯）/膨胀石墨纳米复合材料的合成及性能

在这项工作中，我们通过一种新的聚合方法合成了聚甲基丙烯酸甲酯（PMMA）/膨胀石墨（EG）纳米复合材料。通过这种方式制备的纳米复合材料的体积电导率非常高（当EG的含量为约8wt％时，电导率可以达到60S / cm）。通过SEM，TEM，IR和XRD研究了纳米复合材料的结构。并且我们发现温度和电压是控制PMMA / EG纳米复合材料电导率的重要参数。©2006 Wiley Periodicals，Inc. J Appl Polym Sci 100：1427–1431，2006
