摘　　要：采用原位聚合的方法制备碳纳米管/石墨烯杂化材料,透射电镜表征了该杂化材料的三维结构。通过碳纳米材料在乙醇溶液中的分散性实验,研究碳纳米材料与有机溶剂之间的界面性能。接着,按照0.3%(质量分数)的比例将碳纳米管、石墨烯以及碳纳米管/石墨烯杂化材料分别分散在环氧树脂中,通过DSC测试,分析杂化材料对环氧树脂固化行为的影响。结果表明:碳纳米管/石墨烯杂化材料在乙醇溶液中分散最稳定,同时杂化材料这种良好的分散性使其与树脂基体结合更为紧密,在树脂的固化过程中起到较好的促进作用。The carbon nanotubes/graphene nanoplateles hybrid material was prepared using in situ grafting method,then the TEM photos showed the 3-dimensional structure of this hybrid material.The interface property between nanomaterials and organic solvent were analyzed though the dispersion experiment in ethanol.Then,according to the proportion of0.3wt%,carbon nanotubes,graphene and carbon nanotubes/graphene nanoplateles hybrid material were dispersed into epoxy resin to investigate the curing behavior of epoxy nanocomposites by DSC test.The results showed that hybrid material put up the most stable dispersion in ethanol.Meanwhile,the hybrid material with the favorable dispersibility provided more strict combination in the resin matrix.Therefore,it played a good role in promoting curing process.
