Abstract

Carbon-based lightweight, thin, and self-standing composite film/paper could be a promising material for electromagnetic shielding applications because of their high flexibility, good electromagnetic properties, and high electrical conductivity. In this paper, a new-type composite of reduced graphene oxide (rGO) and Fe3O4 nanoparticles (F-NPs) has been investigated for potential applications in electromagnetic microwave absorbing film. The results indicated that with increasing the loading of F-NPs in the films, the values of saturation magnetization increased, contributing to an enhanced permeability of rGO/F-NPs composite films, while the dielectric loss decreased corresponding to a low conductivity. A maximum reflection loss of -11.04 dB was obtained at 5.19 GHz for the composite with 100 mg graphene oxide and 200 mg F-NPs with a matching thickness of 3.0 mm, and the effective absorption bandwidth with reflection loss values less than -10 dB covered 2.8-8.6 GHz.
