摘　　要：新型碳基磁性复合吸波材料因兼具质轻和高性能而成为当今电磁波吸收材料的研究主流。碳系吸波材料既有密度小、比表面大、电导率高等优点,也存在无磁性、阻抗匹配水平低等不足,常通过与磁损耗物质复合来构筑多样微结构、多元协同损耗机制的轻质复合材料,实现高强与宽频电磁波吸收。本文在总结国内外碳基复合材料吸波应用的研究基础上,以成分组成、复合方法、微观结构等为主线对比分析了新型石墨烯、碳纳米管、生物质多孔碳及其他碳系磁性复合吸波材料的研究进展,并指出了磁性碳系吸波材料存在的问题及未来发展趋势。New carbon based magnetic composite absorbing materials have become the mainstream of electromagnetic wave absorbing materials because of their light weight and high performance.Carbon based wave absorbing materials have the advantages of low density,large specific surface,high conductivity,but also have the disadvantages of non-magnetic and low impedance matching level.They are often combined with magnetic loss materials to build light composite materials with various microstructures and multiple cooperative loss mechanisms to achieve efficient and broadband electromagnetic waveabsorption.On the basis of summarizing the research on the wave absorbing application of carbon matrix composites at home and abroad,this paper analyzes the research progress of new graphene,carbon nanotubes,biomass porous carbon and other carbon matrix magnetic composite wave absorbing materials with composition,composite method and microstructure as the main line,and finally points out the existing problems and future development trend of carbon based magnetic absorbing materials.
