Abstract

In order to prevent the microwave leakage and mutual interference, more and more microwave absorbing devices are added into the design of electronic products to ensure its routine operation. In this work, we have successfully prepared MoS₂/TiO₂/Ti₃C₂T_x hierarchical composites by one-pot hydrothermal method and focused on the relationship between structures and electromagnetic absorbing properties. Supported by comprehensive characterizations, MoS₂ nanosheets were proved to be anchored on the surface and interlayer of Ti₃C₂T_x through a hydrothermal process. Additionally, TiO₂ nanoparticles were obtained in situ. Due to these hierarchical structures, the MoS₂/TiO₂/Ti₃C₂T_x composites showed greatly enhanced microwave absorbing performance. The MoS₂/TiO₂/Ti₃C₂T_x composites exhibit a maximum reflection loss value of −33.5 dB at 10.24 GHz and the effective absorption bandwidth covers 3.1 GHz (13.9–17 GHz) at the thickness of 1.0 mm, implying the features of wide frequency and light weight. This work in the hierarchical structure of MoS₂/TiO₂/Ti₃C₂T_x composites opens a promising door to the exploration of constructing extraordinary electromagnetic wave absorbents.
