Published: Dec. 24, 2024

Microwaves are currently used in many fields, including the military, medical, and communication. However, ensuing electromagnetic radiation has seriously threatened human life. Therefore, design of high-performance microwave absorbing materials (MAMs) become an important development direction. Metal-organic frameworks (MOFs) regarded as a bright new star among MAMs with broad application prospects due to their advantages tunable structure, large specific surface area, high porosity, etc . This paper reviews research progress derived from MOFs recent years, preparation methods, properties absorption mechanisms. Finally, problems MOF-derived discussed.

Published: Feb. 10, 2025

Abstract The rational manipulation of interfacial properties, composition, and morphology materials has emerged as an effective strategy for enhancing their microwave absorption performance. crystal phase microstructure, electromagnetic properties can be regulated by varying the thermal treatment temperature. synergistic integration heterogeneous interfaces, magnetic materials, microstructures, defect engineering helps optimize impedance matching enhance polarization losses. Herein, multi‐interface core–shell FeSiAl@MnO x @C composites with various morphologies demonstrated superior A minimum reflection loss −56.3 dB is achieved at absorber thickness 1.41 mm, bandwidth 5.0 GHz obtained a 1.59 mm. radar cross‐section reduction value reached 19.448 incidence angle 0°. excellent performance due to effect significant dielectric losses improved matching. This study establishes foundation designing next‐generation high‐performance microwave‐absorbing high
