The absorption of microwaves is significantly influenced by the structure of the absorber. Typically, the electromagnetic parameters can be adjusted by modifying the structure of the absorber. In this work, a novel approach is proposed to enhance microwave absorption properties by adjusting the impedance matching of MXene nanosheets. MXene/PPy hybrids with loose lamellar structure are synthesized through self-assembly of positively charged polypyrrole (PPy) and MXene nanosheets with negative charges, facilitated by electrostatic and hydrogen-bonding interactions. The impact of polymorphic PPy on the electromagnetic parameters and microwave absorption properties of MXene nanosheets is comprehensively explored. It is found that the addition of PPy with different morphologies can effectively tune the electromagnetic parameters of the MXene nanosheets. Particularly, the microwave absorption capabilities are significantly enhanced when PPy nanopaperclips are uniformly adsorbed on the surface of the MXene nanosheets. This enhancement is attributed to the favorable impedance match between PPy nanopaperclips and MXene nanosheets along with the exceptional attenuation capabilities of PPy. A minimum reflection loss (RLmin) of −47.85 dB is achieved at an ultrathin matched thickness of 1.6 mm, and the maximum effective absorption bandwidth (EABmax) is 5.01 GHz at 1.9 mm for the prepared MXene/PPy nanopaperclip hybrid with a filling rate of 20%. Furthermore, a bandwidth with 99% absorption efficiency of 15.4 GHz (2.4–18.0 GHz) can be attained when the thickness of the absorber ranges from 1.6 to 10.0 mm. It is anticipated that this work will provide valuable insights for the manufacture of high-performance microwave absorbers.

Developing lightweight, high‐performance electromagnetic wave (EMW) absorbing materials those can absorb the adverse electromagnetic radiation or waves are of great significance. Transition metal carbides and/or nitrides (MXenes) are a novel type of 2D nanosheets associated with a large aspect ratio, abundant polar functional groups, adjustable conductivity, and remarkable mechanical properties. This contributes to the high‐efficiency assembly of MXene‐based aerogels possessing the ultra‐low density, large specific surface area, tunable conductivity, and unique 3D porous microstructure, which is beneficial for promoting the EMW absorption. Therefore, MXene‐based aerogels for EMW absorption have attracted widespread attention. This review provides an overview of the research progress on MXene‐based aerogels for EMW absorption, focusing on the recent advances in component and structure design strategies, and summarizes the main strategies for constructing EMW absorbing MXene‐based aerogels. In addition, based on EMW absorption mechanisms and structure regulation strategies, the preparation methods and properties of MXene‐based aerogels with varieties of components and pore structures are detailed to advance understanding the relationships of composition‐structure‐performance. Furthermore, the future development and challenges faced by MXene‐based aerogels for EMW absorption are summarized and prospected.
