Figure 3From: Low percolation threshold of graphene/polymer composites prepared by solvothermal reduction of graphene oxide in the polymer solutionStatic conductivity of the SRG/PVDF composites showing percolative behavior. The red solid lines are nonlinear fits to Equation 1. The conductivity takes the average value of ten samples. Inset is the plot of log σ versus log(p−pc).Back to article page
