摘要
采用溶液共混法制备了以石墨烯和氧化石墨为填料的室温硫化硅橡胶复合材料,并对其导电性能和力学性能进行了研究。结果表明,当石墨烯质量分数为3%时,复合材料的拉伸强度提高200%左右;体积电导率提高了9个数量级,复合材料中石墨烯的逾渗阈值为1%。利用原位热还原法处理氧化石墨/硅橡胶复合材料,当处理时间为30min时,其体积电导率提高了3个数量级。
Abstract： The blending, and the vulcanized silicone rubber composite was prepared by solution ties and conductivity properties of the composites were studied. % graphene, the tensile strength of the composite was increased room temperature mechanical proper The results showed that with only 3 by about 200 %. And the volume conductivity of the graphene/silicone rubber composite was increased by nine orders of magnitude, the percolation threshold of graphene in the composite was 1%. By in si- tu thermal reduction, the volume conductivity of graphite oxide/silicone rubber composites, with the processing time of 30 min, was increased by 3 orders of magnitude.
