The extraordinary performances of polymer-matrix nanocomposites endow them with important fundamental and application research values.Graphene

as the 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 high-performance 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 interfacial interactions between graphene and polymer matrices

including hydrogen bonding

- 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.
