摘　　要：为了防治日益严重的电磁干扰问题,吸波材料的研发越来越引起人们的重视。SiC作为一种介电性能优秀的吸波材料,还具有出众的稳定性、高强度、耐腐蚀等优点,但也有着阻抗匹配不佳、吸波机制单一的缺点。将SiC与其他材料复合是进一步提高SiC材料吸波性能的重要手段。本文简要介绍了SiC的结构、吸波机制及影响因素,详细综述了不同维度的SiC复合材料的吸波性能,包括SiC纳米颗粒、SiC纳米线、三维SiC材料与金属材料、碳材料、陶瓷材料、高分子材料等不同种类材料复合,相比于单一的SiC材料,复合材料可以提高其介电性能、丰富吸收机制、优化阻抗匹配,进而提高吸波性能。最后展望了SiC基复合吸波材料的发展方向。In order to prevent the increasingly serious electromagnetic interference problem,the research and development of microwave absorbing materials has attracted more and more attention.As a microwave absorbing material with excellent dielectric properties,SiC also has the advantages of excellent stability,high strength and corrosion resistance.But it also has the disadvantages of poor impedance matching and single microwave absorbing mechanism.Compounding SiC with other materials is an important means to further improve the microwave absorbing properties of SiC materials.The structure,microwave absorbing mechanism and influencing factors of SiC were briefly introduced in the paper.Then the microwave absorbing properties of SiC composites with different dimensions were summarized in detail,including SiC nanoparticles,SiC nanowires,three-dimensional SiC materials with different kinds of materials such as metallic materials,carbon materials,ceramic materials,and polymer materials.Compared with a single SiC material,the composite materials can improve their dielectric properties,enrich the absorption mechanism,optimize the impedance matching,and then improve the microwave absorption ability.Finally,the development direction of SiC based composite microwave absorbing materials was prospected.
