Recent Progress and Outlook on the Emerging Low-Dimensional MoS2 Nanostructures for Microwave Absorption

To tackle the deteriorating electromagnetic interference and pollution problems, enhanced microwave absorption materials are urgently being developed. Low-dimensional molybdenum disulfide (MoS2) nanostructures have been comprehensively researched and employed as microwave absorption materials in virtue of their tailorable valence bands, ample active polarization sites, appropriate electronic band configuration, ample morphologies, distinctive dielectric, and electric behaviors. The excellent merits are expected to satisfy the extensive and unique application requirements. Low-dimensional MoS2 nanostructure microwave absorption materials excel in ultrathin thickness, lightweight, broad effective absorption bandwidth, and strong attenuation capability. The advantages are due to well-matched impedance matching, multiple polarization relaxations, and multiple reflections and scatterings effect. This review sketches up the theories on microwave propagation, attenuation, and performance evaluation. Simultaneously, the preparation methods of low-dimensional MoS2 nanostructures are elaborately categorized. More importantly, the cutting-edge research progresses on low-dimensional MoS2 nanostructures for microwave absorption are thoroughly combed. Finally, some perspectives and challenges for the future orientation of low-dimensional MoS2 nanostructures are highlighted. Without doubt, low-dimensional MoS2 nanostructures have illuminated boundless roadmaps for further advancement as high-performance microwave absorption materials.
