Abstract

MnFe₂O₄ nanoparticles have been synthesized on a large scale by a simple hydrothermal process in a wild condition, and the RGO/MnFe₂O₄ nanocomposites were also prepared under ultrasonic treatment based on the synthesized nanoparticles. The absorption properties of MnFe₂O₄/wax, RGO/MnFe₂O ₄/wax and the RGO/MnFe₂O₄/PVDF (polyvinylidene fluoride) composites were studied; the results indicated that the RGO/MnFe ₂O₄/PVDF composites show the most excellent wave absorption properties. The minimum reflection loss of RGO/MnFe₂O ₄/PVDF composites with filler content of 5 wt % can reach -29.0 dB at 9.2 GHz, and the bandwidth of frequency less than -10 dB is from 8.00 to 12.88 GHz. The wave absorbing mechanism can be attributed to the dielectric loss, magnetic loss and the synergetic effect between RGO+MnFe₂O ₄, RGO+PVDF and MnFe₂O₄+PVDF.
