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

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 RL min 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 m 2 . Integrating multiple functions such as thermal insulation, sensing, and microwave absorption into one material—MXene/C aerogel.
