Abstract
With the rapid development of radio waves and electronic information technology,the problem of electromagnetic radiation pollution is becoming more and more prominent,which has attracted wide attention around the world.In order to solve the problem of electromagnetic pollution,people are committed to researching and developing electromagnetic wave-absorbing materials with light weight,thin thickness,a wide frequency band,and strong absorption.Compared with traditional wave-absorbing materials,carbon-based composite wave-absorbing materials have excellent dielectric properties,special microstructure,good impedance matching and efficient wave-absorbing properties,and can effectively reduce the mass of composite materials,which has great development potential in the field of wave-absorbing materials,and has gradually become a research hotspot.In this paper,the basic absorption principle of electromagnetic wave is summarized from the aspects of impedance matching and loss mechanism,and the research progress of carbon-carbon,carbon-metal/metal oxide,carbon-ceramics and other kinds of carbon-based composite absorbing materials is reviewed.At the same time,the synthesis methods,absorption properties and attenuation mechanism of these carbon-based composite absorbing materials are reviewed.Finally,the shortcomings of carbon-based composite absorbing materials in electromagnetic wave absorption are discussed and possible solutions are put forward,and the future development direction of carbon-based composite absorbing materials is prospected.
