摘要

Zinc oxide nanosheet/zinc-covered carbon fiber composites (ZNSZCFs) were synthesized by annealing the zinc-covered carbon fibers with electroplating in air. The diameter of the ZNSZCFs was about 25 渭m. The strongest RL of ZNSZCFs was 鈭?2.98 dB at 3.31 GHz. The strong absorption of ZNSZCFs was less than 鈭? dB (>65%) over the range of 7.54-18 GHz (1.6 mm in thickness) and 5.96-18 GHz (2.0 mm in thickness), respectively. The ZNSZCFs are believed to be ideal microwave absorbing materials.
