摘　　要：采用球磨法制备不饱和聚酯树脂/石墨烯纳米复合材料,并对其力学性能、动态力学性能和导电性能进行研究.结果表明:石墨烯微片经过球磨被剥离成厚度低于5层的石墨烯;制备的不饱和聚酯树脂石墨烯复合材料与纯的不饱和聚酯树脂相比,当石墨烯的质量分数为0.5%时,复合材料的拉伸强度、杨氏模量、弯曲强度均达到最大值,分别提高44.99%,47.67%和55.08%;复合材料的冲击性能基本不受石墨烯加入的影响;且复合材料的渗滤阀值为6%.Unsaturated polyester resin（UPR）/graphene nanocomposite was prepared by ball milling in this paper.The mechanical,conductivity properties and the dynamic mechanical properties of the composites were studied.It was found that the graphene in the composite was fewer than 5 layers.When the mass fraction of graphene is 0.5%,the tensile strength,the Young＇s modulus and flexural intensity of the composite material reached the maximum,respectively improved 44.99%,47.67% and 55.08%.Their impact strength was not affected by the loading of graphene.The percolation threshold of the nanocomposite was 6%.
