A novel three-dimensional Fe3SnC/C hybrid nanofiber absorber for lightweight and highly-efficient microwave absorption

Abstract

3D Fe₃SnC/C hybrid nanofibers are proposed as a novel high-performance microwave absorber. At only 20 wt% filler loading, the optimal reflection loss reaches −119.2 dB at 17.1 GHz and the effective absorption bandwidth is 7.4 GHz with a thickness of 2.3 mm, outperforming most of the reported absorbers.
