Preparation and microwave absorption properties of FeNi/graphite nanocomposites
FeNi/graphite nanocomposites were prepared by reducing FeCl3-NiCl2-GlCs in H2. The elemental composition, structure, magnetic and microwave absorption of FeNi/graphite nanocomposites were investigated using X-ray diffraction, energy dispersive spectra, hysteresis loop and electromagnetic parameter a...

| description | FeNi/graphite nanocomposites were prepared by reducing FeCl3-NiCl2-GlCs in H2. The elemental composition, structure, magnetic and microwave absorption of FeNi/graphite nanocomposites were investigated using X-ray diffraction, energy dispersive spectra, hysteresis loop and electromagnetic parameter analysis. The results show that with the increase of the reduced temperature, the number and size of particles of FeNi increases, and the FeNi/graphite nanocomposites changes to soft magnetism. FeNi/graphite nanocomposites bear microwave absorption properties. With the increase of the thickness of the sample, the matching frequency tends to shift to the low frequency region, and theoretical reflection loss becomes less at the matching frequency. Microwave absorption property in the low frequency region of FeNi/graphite nanocomposites prepared at 600 ℃ （FeNi/C600） is the best. When the thickness is 2 ram, the maximum theoretical reflection loss of FeNi/C600 is -4.3 dB and the matching frequency is 3.5 GHz. |
