碳纳米管复合吸波材料研究进展

Research Progress in Composite Absorbing Materials of Carbon Nanotubes(CNTs)

电磁波吸收材料在国防民生等领域有重要的应用,早期的吸波材料主要采用的是铁氧体、磁性金属微粉等,这些材料具有高密度,窄吸收频带等缺点,极大地限制了其实际应用。为实现对电磁波"薄轻宽强"的吸收效果,研发新型高效吸波材料意义重大。文章对近年来碳纳米管复合吸波材料的发展状况作了简要的介绍,并对未来碳纳米管基复合吸波材料的发展趋势进行了展望。

Electromagnetic wave absorbing materials have important applications in the fields of national defense and people＇s livelihood. The early absorbing materials mainly used ferl＇ite, magnetic metal powder and so on. These materials have the shortcomings of high density, narrow absorption frequency band and so on. It greatly limits its practical application. In order to realize the absorb- ing effect of electromagnetic wave ＂thin, light, wide and strong＂, it is of great significance to develop a new type of high efficient absorbing material. In this paper, the development of carbon nanotube composite absorbing materials in recent years is briefly intro duced, and the development trend of carbon nanotuhe based composite absorbing materials in the future is prospected.
