Synthesis and microwave absorption properties of Fe@carbon fibers

Year: 2020

Type: article

Abstract: reduction. The surface morphology, lattice structure and element composition of the synthesized Fe@carbon fibers were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy disperse spectroscopy (EDS) respectively. Based on these qualitative analyses, a possible growth mechanism was proposed for guide production. In order to investigate their electromagnetic absorbing properties, electromagnetic parameters of Fe@carbon fibers-paraffin composites have been evaluated by coaxial reflection/transmission technique. The Fe@carbon fibers-paraffin composites containing different particle contents were prepared to clarify the optimum material ratio. The results showed that the composite loaded with 30 wt% carbon fibers@Fe particles exhibited the most prominent microwave absorption, with strong absorption (maximum reflection loss of -39.8 dB), effective absorption bandwidth (2.9 GHz) and small thickness (1.5 mm).
