摘　　要：通过熔融混合法,将热还原氧化石墨/PP-g-MA母料添加到非极性聚烯烃共混物PP/POE中,制备得到石墨烯以很少片层堆积在非极性聚烯烃共混物中的纳米复合材料。X射线衍射和透射电镜分析表明热还原氧化石墨在PP/POE中分散较好。因而热还原氧化石墨对体系的结晶具有较好的成核作用,同时赋予其良好的电学性能,导电逾渗阈值为1.5%。此外,复合体系的热稳定性能显著提高。PP-g-MA was compounded with graphene to obtain masterbatch, followed by melt blending with PP/POE using a micro-compounder. XRD and TEM Investigation showed the homogeneous dispersion of graphene in PP/POE with few layers. Therefore, the thermal reduction of graphite oxide has a good nucleation effect on the crystallization of the system, and gives a good electrical performance at the same time, and the conductivity percolation threshold is 1.5%. In addition, the thermal stability of the composite system is remarkably improved.
