摘要：
Graphene nanoplatelet (GNP)-epoxy compositeswere fabricated for the investigation of the dielectric permittivity and microwave absorption in a frequency range from 8 to 20 GHz. The intrinsically conductive GNP particles and polarized interfacial centers in the composites contribute to the microwave absorption. A minimum reflection loss of - 14.5 dB at 18.9 GHz is observed for the GNP-epoxy composites with 15 wt. % GNP loading, which is mainly attributed to electric conductivity and the charge multi-poles at the polarized interfaces in the GNP-epoxy composites.
