Abstract

Graphene nanosheets/epoxy resin (GN/EP) composites with enhanced microwave absorption properties were prepared. The influence of GNs content on the electromagnetic and microwave-absorbing properties of single-layer GN/EP composites was investigated in the frequency range of 2–18[Formula: see text]GHz. A novel double-layer microwave absorber by combining absorbers with different contents of graphene was designed to achieve absorbers with wide absorption band and optimal microwave absorption. The calculated microwave absorption properties indicated that broader absorption band was obtained by the double-layer GN/EP composites. Reflection loss (RL) values below [Formula: see text]5[Formula: see text]dB can be obtained in the frequency range of 4.4–18[Formula: see text]GHz by the double-layer GN/EP composites at thickness of 3.9[Formula: see text]mm.
