Research Progress in Composite Absorbing Materials of Carbon Nanotubes(CNTs)
Electromagnetic wave absorbing materials have important applications in the fields of national defense and people's livelihood. The early absorbing materials mainly used ferrite, 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 absorbing 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 introduced, and the development trend of carbon nanotube based composite absorbing materials in the future is prospected.
