摘要
采用十八烷基胺对氧化石墨烯进行表面改性,用硼氢化钠对其进行还原,得到功能化石墨烯(ARG),并通过溶液复合法制备ARG/溶聚丁苯橡胶(SSBR)复合材料,对其性能进行研究。结果表明:ARG在SSBR基体中的分散较为均匀;加入ARG的复合材料的物理性能明显提高;当ARG用量为3份时,复合材料达到了导电渗流阈值;当ARG用量为12份时,复合材料的导电性能最佳;随着ARG用量的增大,复合材料的介电常数增大。
Functionalized graphene(ARG)was obtained by surface modification of graphene oxide using octadecylamine and then reduction by sodium borohydride.Subsequently,the ARG/solution polymerized styrene-butadiene rubber(SSBR)composite was prepared through solution compounding method,and its properties were investigated.The results showed that,ARG was dispersed well in SSBR matrix.The physical properties of the composite filled with AGR were obviously improved.The conductive percolation threshold in the composite appeared at 3 phr ARG.When the addition level of ARG was 12 phr,the conductivity of the composite were the best.As the addition level of ARG increased,the dielectric constant of the composite increased.
