轻质核壳结构吸波材料的研究进展

Development Research on Lightweight Core-Shell Structure Microwave Absorption Materials

随着现代科技的发展,电磁波辐射对人类的影响越来越大,在电子电路中释放的电磁波会破坏其他设备的性能并且损害人体健康,因此吸波材料的研究显得尤为重要。此外,具有优良电磁性能的复合吸波材料还可以用于制备飞行器隐身材料。这是因为高强度的微波吸收材料具有良好的介电损耗和磁性损耗,同时具有优越的阻抗匹配,而核壳结构的吸波材料是复合吸波材料中较为理想的材料。本文详细介绍了核壳结构吸波材料的合成方法,并根据核壳结构材料的分类及具体应用,阐述了近年来国内外核壳结构吸波材料的最新研究进展。

With the development of technology, electromagnetic wave radiation has more and more influence on people. The e- lectromagnetic wave emitted from electronic circuitry may destroy the performance of other devices and affect human health. Thus, it will be of great importance to pay attention to the research and development of electromagnetic wave absorption materi- als. Moreover, the composite absorbing materials with excellent electromagnetic properties can also be used to make aircraft steahh materials. That＇ s because microwave absorption materials are developing toward the direction of composite materials, which possess dielectric loss and magnetic loss. At the same time, they have required for high performance electromagnetic wave absorption materials core-shell structure material is one of the ideal and outstanding materials among all the excellent composite microwave absorption materials. In this paper different synthetic methods of core-shell structure material and its development tendency were introduced in detail. And from its classification and application, we illustrate its current progress at home and a- board over the years.
