Abstract
- Transition metal dichalcogenide MoS<subscript>2</subscript> is considered as a type of dielectric loss dominated electromagnetic wave absorbing material owing to the high specific surface area, layered structure, and lightweight. Introduction of interfaces will improve the electromagnetic wave absorbing performance. Here, the phase engineering of MoS<subscript>2</subscript> is realized through W doping since of the microstrain effect, resulting in the appearance of 2H/1T MoS<subscript>2</subscript> phase interface. Furthermore, MoS<subscript>2</subscript>/Ti<subscript>3</subscript>C<subscript>2</subscript> MXene interface is realized through the construction of MoS<subscript>2</subscript>/Ti<subscript>3</subscript>C<subscript>2</subscript> MXene heterostructure, leading to obvious improvements in electromagnetic wave absorbing. Because of the simultaneous introduction of 2H/1T MoS<subscript>2</subscript> phase interface and the MoS<subscript>2</subscript>/Ti<subscript>3</subscript>C<subscript>2</subscript> MXene interface, the microwave reflection loss can reach −45.2 dB with broad effective absorption bandwidth (<−10 dB) of 7.1 GHz (7.8–14.9 GHz) at the same thickness of 3 mm. The results shed light on enhancing electromagnetic wave absorbing performance by phase engineering as well as construction of two dimensional material/two dimensional material heterostructures, thereby introducing multiple interfaces.
