The influences of the mass fraction of the iron nanofibers on the microwave electromagnetic and absorbing properties of the iron nanofibers/carbonyl iron particles composites were investigated. The results showed that the complex permittivity and permeability of the composites increased with the increase of the mass fraction of the iron nanofibers. The absorbing coatings based on the composites consisting of 2.2-4.4 wt% iron nanofibers exhibited a broader bandwidth and lower surface density than that of the absorbing coatings based on carbonyl iron particles, which was attributed to the enhancing of the matching and absorbing properties of the absorbing coatings through the increase of the complex permittivity of the absorbent in an appropriate range. Thereforre, a new method was provided for the preparation of the light absorbing absorbing coatings with broad bandwidth.
