%X 分别采用热解还原法和溶液法制备石墨烯（TrG）和TrG/硅橡胶（MVQ）复合材料，并对TrG/MVQ复合材料的导电性能和物理性能进行研究。结果表明：TrG能够明显提高MVQ的导电性能，随着TrG用量的增大，TrG/MVQ复合材料的体积电阻率明显降低，TrG的渗滤阈值为0.019 4；TrG对MVQ具有补强作用，随着TrG用量的增大，TrG/MVQ复合材料的邵尔A型硬度和拉伸强度明显提高；TrG在MVQ基体中分散良好，部分互相交错搭接在一起，形成了贯通的导电网络。;Graphene（TrG） was prepared by using a thermal reduction method，the TrG/silicone rubber （MVQ） composites were prepared via solution method，and the electrical conductivity and physical properties of TrG/MVQ composites were investigated.The results showed that，TrG could significantly improve the electrical conductivity of MVQ，and with the increase of addition level of TrG，the volume resistivity of TrG/MVQ composite was decreased obviously.The percolation threshold of TrG was 0.019 4.TrG also showed reinforcing effect in MVQ，and with the increase of addition level of TrG，the Shore A hardness and tensile strength of TrG/MVQ composite increased significantly.TrG could be well dispersed in MVQ matrix and the grapheme sheets stacked and interlaced together，so that TrG could form a conductive network through MVQ
