摘要

The development of wave-absorbing materials is of particular crucialness in dealing with electromagnetic wave (EMWs) pollution. Especially in the fields of aerospace and highly integrated electronic devices, where the demand for lightweight, high-efficiency, broadband and multi-functional EMWs absorbing materials is increasing gradually. In this study, through the synergistic regulation of hybrid fillers and micro-nano structures, an EMWs absorbing material with abundant heterogeneous interfaces and micro-nano pore structures has been successfully formed. The prepared Ti₃C₂Tₓ MXene@CoFe-MOF@chitosan carbon aerogel significantly enhances the absorption performance of EMWs by stimulating heterogeneous interface polarization relaxation and electromagnetic synergy effects. Under the condition of low density (35.09 mg/cm3), TMC900 exhibits a minimum reflection loss of -50.95 dB and an effective absorption bandwidth (EAB) of 6.1 GHz. In addition, TMC900 also possesses excellent heat insulation and flame-retardant characteristics, enabling it to be applied in extreme environments. This research clarifies the synergistic regulation mechanism of hybrid fillers and micro-nano structures, opening a new pathway for the design of heterogeneous structures in EMWs absorbing materials.
