摘　　要：采用乳液共凝聚的方法得到预分散的羧基丁腈橡胶(XNBR)/石墨烯复合材料,再将聚氯乙烯(PVC)与XNBR/石墨烯复合材料通过熔融复合制备PVC/石墨烯纳米复合材料。采用透射电镜表征了石墨烯在XNBR中的分散性,并研究了石墨烯含量对PVC/石墨烯纳米复合材料拉伸强度、硬度、电性能和热稳定性能的影响。结果表明,PVC/石墨烯纳米复合材料的力学性能、热稳定性能和导电性明显提高。石墨烯含量为0.05%时,石墨烯片层在PVC中充分分散,形成导电通路,当含量达到1%时,复合材料的电导率由2.74×10-15S/cm提高到1.06×10-6S/cm。The pre-dispersing carboxy nitrile rubber （XNBR）/graphene composite was prepared by latex heterocoagulation. Then poly （vinyl chloride） （PVC）/graphene nanoeomposite was prepared by melt method using XNBR/grapheme composite. The dispersity of graphene in XNBR was investigated by transmission electron microscope. And the effects of graphene content on tensile strength, hardness, electrical properties and thermostability of the composite were analyzed. The results showed that the mechanical properties, thermostability and conductivity of the nanocomposites increased obviously. It was found that 0. 05% graphene could be well dispersed in PVC matrix, forming a conductive path. With the graphene addition amount of 1%, the electrical conductivity of composite increased from 2.74×10^-15 S/cm to 1.06×10^-6 S/cm.
