摘　　要：首先合成含有6个羟基的三亚苯衍生物,并通过铈盐和羟基组成的氧化还原体系合成星型聚丙烯腈(SPAN)。利用星型聚丙烯腈和石墨烯之间的π-π键相互作用合成易于分散的星型聚丙烯腈/石墨烯复合材料,再利用改性后的石墨烯对ABS进行共混改性。研究了改性石墨烯的加入对ABS力学性能和电学性能的影响。First triphenylene derivative containing six hydroxyl groups was synthesized,and then a star-shaped polyacrylonitrile（SPAN） was obtained by the redox system of tetravalent cerium salt and hydroxyl groups.A easily dispersed star-shaped polyacrylonitrile/graphene composite was prepared by π-π interactions between star-shaped polyacrylonitrile and grapheme sheets.Finally the modified graphene was applied to modify ABS.The effect was studied on mechanical and electrical properties of ABS since the addition of modified graphene.
