With rapid technological advancements, electromagnetic radiation is becoming one of new forms of pollution, which not only affects the use of precision instruments, but also threatens the safety of human life. Electromagnetic wave (EMW) absorbing material can effectively attenuate EMW, among which carbon fiber doped magnetic particles possess low density, multiple attenuation, and magnetic-dielectric synergy, attracting more and more attention. Carbon-based magnetic fibers achieve the combination of magnetic loss and dielectric loss, and effectively improve impedance match, resulting in excellent reflection loss (RL) and effective absorption bandwidth (EAB). Herein, recent researches on carbon-based magnetic fibers are reviewed, focusing on the preparation methods and structural difference. It also specifically introduces their absorption performance and structural advantages, providing a brief analysis of their structure-property relationship. Finally, the extensive application potential of carbon-based magnetic fibers is emphasize, highlighting the challenges and opportunities in the field of EMW absorption.
