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.
