In this paper, based on developing an analytical model, the effective electrical conductivity and percolation behavior of exfoliated polymer graphene nanocomposites (PGNs) are investigated. The graphene layers are considered as filleted cuboids which are randomly distributed in the matrix. The effects of several parameters including physical properties of graphene, matrix, interphase region, and quantum tunneling effect on the effective electrical conductivity and percolation behavior of PGNs are investigated. Moreover, comparing our results with the results obtained for graphene disc and cuboid composites, the present model makes a better prediction of the electric behavior of the compound. Afterward, our results are compared with five different experimental data sets and satisfactory agreement were found.
