MXene-Based Composite Electromagnetic Absorbers: from Micromorphology Design to Electromagnetic Wave Absorption Performance

MXene has become a potential electromagnetic absorbing material due to its controllable and excellent electromagnetic parameters, which have attracted extensive attention from researchers. However, due to the two-dimensional nanosheet structure of MXene and the rich polar functional groups on its surface, the dispersion of MXene in the process of assembling composites becomes a challenge. Herein, from the perspective of preparation methods, the micromorphology design ideas and the corresponding electromagnetic absorbing performance of MXene-based absorbing composite materials in recent years are reviewed. Through the meticulous material structure design strategy, MXene-based composites are expected to become tunable electromagnetic wave absorbing materials with superior performance.
