Lightweight and High-Performance Microwave Absorber Based on 2D WS(2)–RGO Heterostructures
Two-dimensional (2D) nanomaterials are categorized as a new class of microwave absorption (MA) materials owing to their high specific surface area and peculiar electronic properties. In this study, 2D WS(2)–reduced graphene oxide (WS(2)–rGO) heterostructure nanosheets were synthesized via a facile h...

description | Two-dimensional (2D) nanomaterials are categorized as a new class of microwave absorption (MA) materials owing to their high specific surface area and peculiar electronic properties. In this study, 2D WS(2)–reduced graphene oxide (WS(2)–rGO) heterostructure nanosheets were synthesized via a facile hydrothermal process; moreover, their dielectric and MA properties were reported for the first time. Remarkably, the maximum reflection loss (RL) of the sample–wax composites containing 40 wt% WS(2)–rGO was − 41.5 dB at a thickness of 2.7 mm; furthermore, the bandwidth where RL < − 10 dB can reach up to 13.62 GHz (4.38–18 GHz). Synergistic mechanisms derived from the interfacial dielectric coupling and multiple-interface scattering after hybridization of WS(2) with rGO were discussed to explain the drastically enhanced microwave absorption performance. The results indicate these lightweight WS(2)–rGO nanosheets to be potential materials for practical electromagnetic wave-absorbing applications.
