Graphene

a 2D honeycomb-like nanocarbon material with high specific surface area

excellent electrical/ thermal conductivity and ideal mechanical properties

is emerging as a desirable reinforced filler for the fabrication of polymer-based composites. Three-dimensional graphene-polymer composites (3DGPCs) can not only fully utilize the exceptional properties of two-dimensional graphene nanosheet

but also desirably impart characteristics of 3D porous material. Solid 3DGPCs fabricated by backfilling polymer into three-dimensional graphene network have the ability to achieve uniform dispersion in polymeric matrix

thus significantly improving its mechanical

electrical and thermal properties. Porous 3DGPCs based on three dimensional graphene framework is characteristic of high porosity

large surface area and outstanding electrical conduction ability

holding significant potential applications in energy storage

environmental protection

sensor

electromagnetic interference shielding and oil pollution clean

and so forth. In this paper

fabrication methods for 3DGPCs are reviewed

and a brief perspective on the challenges and future opportunities is concluded.
