Novel core-shell structured Fe@Al₂O₃ nanofibers by atomic layer deposition as a high-performance microwave absorbent
Abstract
Novel 3D Fe-NFs@Al2O3 composite nanofibers are developed as an advanced microwave absorption material. The minimum reflection loss can achieve -57.9 dB at 13.6 GHz at 1.65 mm with 30 wt% filler loading and the widest effective absorption bandwidth is 4.56 GHz within 10.4-14.96 GHz with 1.7 mm.
