摘要：

Microwave absorption composites consisting of Ce2Fe17N3-delta and various weight ratios of multi-walled carbon nanotubes (MWCNTs) (0, 0.5, 1, 1.5 wt%) as absorbers were prepared, and their microwave absorption performance was investigated. The results show that the composites attain increasing complex permittivity as the loading ratio of MWCNTs increase, whereas the permeability is almost unaffected. The composite filled with 0.5 wt% of the MWCNTs had a minimum reflection loss (RL) of -48.7 dB and effective absorption bandwidth (EAB, with an RL of less than -10 dB) of 5.5 GHz at a thickness of 1.4 mm. Owing to the balance of the ameliorated impedance conditions and the synergetic effect of dielectric and magnetic loss, the microwave absorption performance was enhanced significantly.
