Claim Text:
1. A graphene polymer composite material, comprising: a plurality of nano-scaled graphene sheets being 0.01-20 wt % (weight percent) of the graphene polymer composite material; a matrix resin being 40-99 wt % of the graphene polymer composite material; and a filler being 1-40 wt % of the graphene polymer composite material, wherein the nano-scaled graphene sheets are dispersed in the matrix resin, the filler is in contact with the plurality of nano-scaled graphene sheets so as to construct an electrically conductive network structure, wherein a thickness of the plurality of nano-scaled graphene sheets is 10-100 nm, a lateral size of the plurality of nano-scaled graphene sheets is 1-100 μm, and a ratio of a particle size of the filler to the thickness of the graphene sheet is 2-1000, and wherein the plurality of nano-scaled graphene sheets has at least one surface-modified layer formed by covering at least one surface modifying agent, the surface modifying agent is selected from a coupler having a chemical formula specified by M
