Novel composites with a segregated structure have been prepared through coating graphene oxide(GO) on poly(vinylidene fluoride) (PVDF) powders and then were hot pressed at 200oC for 2h to form composites. During hot-pressing, the graphene oxide was turned into reduced graphene oxide. The resulting composites with graphene as conductive filler formed a two-dimensional conductive network and exhibited a low value of the percolation threshold. The image of GO-coated PVDF powders was observed by scanning electron microscopy (SEM). The dielectric permittivity of the graphene/PVDF composites as a function of frequency with different graphene volume fraction were shown at room temperature. The composite of filler content 0.263 vol% exhibits higher dielectric constants (225) and smaller loss factor (7.9) at 1000Hz.
