![]() The results show that the maximum reflection loss (RL) could reach to −59.6 dB, and the maximum effective absorption bandwidth (RL < −10 dB) achieved 4.6 GHz with only 1.43 mm thickness. The morphology, microstructure, magnetic properties, and microwave absorption performance of the composite nanofibers were characterized in detail. In this paper, carbon/SiO 2 core-sheath nanofibers with Co-Fe nanoparticles embedded in were synthesized by electrospinning and carbonization. As an excellent microwave absorption material, the in-depth study of carbon-based nanofibers’ absorbing mechanism is of great significance for subsequent applications.
