Multifunctional MXene/C Aerogels for Enhanced Microwave Absorption and Thermal Insulation

Abstract

Highlights Curving 2D MXene into 1D nanofibers can effectively stop the restacking of MXene flakes, and then the nanofibers are used to construct a lightweight and multifunctional MXene/C aerogel. The MXene/C aerogels achieved an RLmin of − 53.02 dB and EAB of 5.3 GHz. The radar cross-sectional reduction value of MXene/C aerogels can reach 12.02 dB m2. Integrating multiple functions such as thermal insulation, sensing, and microwave absorption into one material—MXene/C aerogel.
