Abstract

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.

杂化-微纳结构设计对Ti₃C₂Tx MXene@CoFe-MOF@壳聚糖异质结的协同效应增强了对电磁波的吸收

吸波材料的发展对处理电磁波污染具有特别重要的意义。特别是在航空航天和高度集成的电子器件领域，对轻量化、高效率、宽频带和多功能的电磁波吸收材料的需求日益增加。本研究通过杂化填料和微纳结构的协同调控，成功形成了具有丰富非均相界面和微纳孔结构的电磁波吸波材料。制备的Ti₃C₂TₓMXene@CoFe-MOF@壳聚糖碳气凝胶通过激发非均相界面极化弛豫和电磁协同效应，显著提高了emw的吸收性能。在低密度（35.09 mg/cm3）条件下，TMC900的最小反射损耗为-50.95 dB，有效吸收带宽（EAB）为6.1 GHz。此外，TMC900还具有优异的隔热和阻燃特性，可应用于极端环境。本研究阐明了杂化填料与微纳结构的协同调节机制，为emw吸波材料的异质结构设计开辟了新的途径。

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
