Development Research on Lightweight Core-Shell Structure Microwave Absorption Materials

With the development of technology, electromagnetic wave radiation has more and more influence on people. The electromagnetic 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 materials. Moreover, the composite absorbing materials with excellent electromagnetic properties can also be used to make aircraft stealth 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 aboard over the years.
