摘　　要：石墨烯是一种二维材料,具有极其优异的电学、力学、热学等性能,制备方法简单且价格低廉,可以在高性能聚合物基复合材料中展现无穷魅力.石墨烯在聚合物中的分散状态,以及与基体间的界面作用是构筑高性能石墨烯/聚合物纳米复合材料的关键因素.本文综述了石墨烯/聚合物纳米复合材料的界面作用力,包括氢键、π-π堆栈、共价、配位作用和成核—结晶作用,并总结和评述了这些界面作用力的优缺点和适用范围.最后展望了多种协同作用在构筑强界面作用力的石墨烯/聚合物基纳米复合材料中的应用前景.The extraordinary performances of polymer-matrix fundamental and application research values. Graphene, as the nanocomposites endow them with important first 2-dimensional material, has outstanding electrical, mechanical and thermal properties. Moreover, its preparation method is easy and inexpensive, and can be scaled up for mass production. Therefore, graphene is one of the most attractive filling materials in highperformance polymer nanocomposites. The dispersity of graphene in a polymer matrix, and the interfacial interaction between the two are key to the exploitation of the nanocomposite performances. In this review, different interracial interactions between graphene and polymer matrices, including hydrogen bonding,π-π stacking, covalent bonding and coordination bonding were summarized. Besides, the advantages and disadvantages of these interfacial interactions, as well as their influences on high-performance polymer nanocomposites were discussed.
