| 中文摘要: |
| 以甲基乙烯基硅橡胶（MVQ）为主体材料、石墨烯为导电填料，制备石墨烯/MVQ导电复合材料，研究石墨烯品种和用量对复合材料物理性能和导电性能的影响。结果表明：石墨烯LKR6963的剥离程度较高、片层较薄、缺陷较少，易在硅橡胶基体中形成导电网络，提高复合材料的导电性能；随着石墨烯LKR6963用量的增大，复合材料的硬度和拉伸强度明显增大，体积电阻率逐渐减小。 |
| 英文摘要: |
| The graphene/methyl vinyl silicone rubber（MVQ） composite was prepared using MVQ as matrix and graphene as conductive filler，and the influence of the type and addition level of graphene on the physical properties and electrical conductive property of the composite was investigated. The results showed that，graphene LKR6963 had a high peeling degree，very thin lamellae and relatively few defects，and it could easily form a conductive network in silicone rubber matrix and improve the electrical conductive property of the composite. As the addition level of graphene LKR6963 increased，the hardness and tensile strength of the composite increased significantly，while the volume resistivity decreased gradually. |
