摘　　要：以石墨烯为填料,反式聚异戊二烯为基体,通过熔融法制备了反式聚异戊二烯/石墨烯纳米复合材料,并对其力学性能进行了探讨。实验结果表明:随着石墨烯含量的增加,复合材料的拉伸强度和断裂伸长率增加。当石墨烯的质量分数为0.05%时,纳米复合材料拉伸强度最大,为44 MPa。添加石墨烯可以显著提高复合材料的力学性能。Graphene nanosheets are chosen as the filler and blended with trans-1,4-polyisprene to fabricate a kind of new hybrid nanocomposite with melting method. Its mechanical properties are investigated. The results show that increasing the content of graphene nanosheets, tensile strength and fracture elongation of the nanocomposite increase. When the content of the graphene nanosheets is 0. 05% ,the tensile strength of the nanocomposite can reach its maximum （44 MPa）,which indicates that the addition of grapheme nanosheets is able to significantly improve the mechanical properties of the nanocomposite.
