▎ 摘  要

The dielectric relaxation behaviour of the composites prepared by solution casting of exfoliated graphene nanoplatelets (xGnP) and ethylene vinyl acetate (EVA) were investigated. The percolation threshold was achieved at 17 phr (parts per hundred rubber) of xGnP loading. Filler contributions to the electrical property were observed by the increase in ac conductivity and permittivity in the composites. The effect of filler loading on the complex and real parts of the impedance were investigated. The effect of temperature on dielectric loss tangent, ac conductivity and Nyquist plot of xGnP reinforced EVA also been studied. A careful comparison of the experimental complex impedance plots and model fitted plots were studied which satisfied the accuracy of the data obtained experimentally.
