摘　　要：研究高性能电磁波吸收材料对提升武器装备隐身性能和解决电磁污染问题具有重大意义。碳化硅(SiC)材料具有良好的耐高温、抗腐蚀和化学稳定性,在电磁波吸收领域展现出良好的应用前景,然而本征SiC材料的吸波性能较弱,如何提升其吸波性能是一个重要的研究课题。本文从SiC材料吸波机理出发,首先分析总结了不同形貌SiC基吸波材料(核壳结构、气凝胶结构、纤维结构、中空结构、MOFs结构等)的研究现状,并详细介绍了SiC与碳化硅纤维、碳材料、磁性物质等复合材料在吸波领域的研究进展,同时综述了特殊类型SiC基吸波材料(SiC基高温吸波材料、SiC基吸波超材料、SiC基多功能吸波材料)的发展现状,最后展望了其未来的发展方向。The research of high-performance electromagnetic wave-absorbing materials(WAM)is of great significance to enhance the stealth performance of weapons and equipment and solve the electromagnetic pollution problem.Silicon carbide(SiC)materials have good resistance to high temperature,corrosion and chemical stability,and show good application prospects in the field of electromagnetic wave absorption.However,the intrinsic properties of SiC materials are weak,and how to improve their wave-absorbing properties is an important research topic.Based on the electromagnetic wave-absorbing mechanism of SiC materials,firstly,the research status of SiC-based WAM with different morphologies(core-shell structure,aerogel structure,fibrous structure,hollow structure,MOFs structure,etc.)is analyzed and summarized.In addition,the research progress of composites of SiC with silicon carbide fibres,carbon materials and magnetic substances in the field of wave absorption is introduced in detail.The development status of special types of SiC-based WAM(SiC-based high-temperature WAM,SiC-based wave absorbing metamaterials,and SiC-based multifunctional WAM)is also reviewed.Finally,the future development direction of SiC-based WAM is prospected.
