| 目的 研究石墨烯微片的添量对石墨烯微片/天然橡胶纳米复合材料性能的影响，并对机械共混法和胶乳共混法进行比较。方法 探索复合材料的制备工艺，利用扫描电镜(SEM)、透射电镜(TEM)、拉曼光谱(RDS)、万能力学试验机等对石墨烯微片和石墨烯微片/天然橡胶纳米复合材料的形貌、结构以及性能进行分析和研究。结果 测试结果表明，石墨烯微片作为填料添加到复合材料中，使复合材料的性能得到了增强。相比纯橡胶而言，石墨烯微片(10 phr)/天然橡胶复合材料的拉伸强度增加了41.5%，热导率增加了153.3%。结论 石墨烯微片可以大幅度提高复合材料的性能，并且胶乳共混法制备的复合材料的性能要优于机械共混法制备的复合材料的性能。 |

| The work aims to study effects of adding graphene nanoplatelets on graphene nanoplatelets/natural rubber nanocomposites, and compare mechanical blending with latex blending. The preparation process of composite materials was studied. The morphology, structure and properties of graphene nanoplatelets and graphene nanoplatelets/natural rubber nanocomposites were investigated via scanning electron microscopy (SEM), transmission electron microscope (TEM), Raman difference spectroscopy (RDS) and universal mechanical testing machine. The results show that the properties of the composites were enhanced by the addition of graphene nanoplatelets. And compared with pure rubber, the tensile strength of graphene nanoplatelets (10phr)/natural rubber composites was increased by 41.5%, and the thermal conductivity of composites was increased by 153.3%. Graphenenano platelets can greatly improve the properties of composites. Properties of composites prepared by latex blending method are better than that prepared by mechanical blending.h |
