英文摘要	The electromagnetic wave interference and pollution have become the significant problems with the rise of electronic technology. The microwave absorbing materials have caught the great interest of the researchers. The traditional absorbing materials, such as iron-based and ceramic-based composites, have some disadvantages such as high density, poor electromagnetic wave absorption performance and narrow absorption bandwidth. However, carbon-based composites have been recently found to be the excellent absorber due to its low density and high conductivity. For example, graphene and carbon nanotubes exhibit excellent electromagnetic wave absorption performance. Graphene and carbon nanotube composites are known to be one of the best microwave absorbing materials. However, the synthesis processes of graphene and carbon nanotube are complex and costly, hindering their industrial applicability. Carbon fibers have the advantages of large-scale production, high thermal stability and good dispersion. Moreover, carbon fibers are the dielectric loss type absorbing material with the lower resistivity (-3 Ω•m). Single carbon fibers cannot be directly used as the microwave absorbing materials. Thus, it is modified to regulate electromagnetic properties and improve the electromagnetic wave absorption performance. In recent years, the electromagnetic wave absorption performance of the carbon fiber composites has been improved with the addition of particle and coa-ting. However, these modified carbon fibers still do not perform as good as carbon nanotube and graphene composites. Therefore, the electromagnetic wave absorption performance of carbon fiber composites should be further improved with the simple and low-cost synthesis method for the large-scale industrial application. In this review, the theory of the electromagnetic wave absorption of the absorbing materials are introduced. Also, the recent research progresses of the carbon micro/nanofiber composites and the carbon spiral fiber composites in the absorption mechanism and properties are summarized. The development trend of the carbon fiber composites with the excellent electromagnetic wave absorption performance is prospected. © 2021, Materials Review Magazine. All right reserved.
