In this study, 2D WS<sub>2</sub>–reduced graphene oxide (WS<sub>2</sub>–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&nbsp;wt% WS<sub>2</sub>–rGO was − 41.5&nbsp;dB at a thickness of 2.7&nbsp;mm; furthermore, the bandwidth where RL &lt; − 10&nbsp;dB can reach up to 13.62&nbsp;GHz (4.38–18&nbsp;GHz). Synergistic mechanisms derived from the interfacial dielectric coupling and multiple-interface scattering after hybridization of WS<sub>2</sub> with rGO were discussed to explain the drastically enhanced microwave absorption performance. The results indicate these lightweight WS<sub>2</sub>–rGO nanosheets to be potential materials for practical electromagnetic wave-absorbing applications.</p> <p>Highlights:</p> <p>1 WS<sub>2</sub>–rGO nanosheets with ultra-small thicknesses and ultra-lightweight, were successfully prepared by a facile hydrothermal method.<br>2 The WS<sub>2</sub>–rGO isomorphic heterostructures exhibited remarkable microwave absorption properties.</p>}, journal={Nano-Micro Letters}, author={Zhang, Deqing and Liu, Tingting and Cheng, Junye and Cao, Qi and Zheng, Guangping and Liang, Shuang and Wang, Hao and Cao, Mao‑Sheng}, year={2019}, month={May}, pages={38} }
