Figure 4From: Low percolation threshold of graphene/polymer composites prepared by solvothermal reduction of graphene oxide in the polymer solutionFrequency dependency of (a) dielectric constant and (b) electrical conductivity of SRG/PVDF composite with various filler contents. Inset in (a) shows dielectric constant versus frequency plots for the composites with 0.1, 0.2, and 0.3 vol.% SRG.Back to article page
