▎ 摘　　要

Graphene, a two dimensional nanomaterial with the layer thickness of only one atom, has aroused tremendous research interests due to its outstanding properties. A new type of nanodielectrics with superior performance can be achieved by introducing graphene nanosheets into polymeric matrices. This review highlighted some recent research progress on graphene/polymer nanocomposites with high dielectric permittivity. The content of this article included the basic theory of percolation,the interface effect of graphene/polymer on the dielectric properties of nanocomposites.
