Performance study of nano Fe3O4/GO aerogel composite materials

Nano Fe 3 O 4 particles were prepared using iron acetylacetonate and benzyl alcohol, and Fe 3 O 4 /GO aerogel composites with mass fractions of 7.5%, 15%, 22.5%, and 30% of nano Fe 3 O 4 particles were obtained by using the nano Fe 3 O 4 particles with graphene oxide. The microstructures of pure GO aerogel and composite aerogels were revealed through scanning electron microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, and X-ray diffraction analysis. The resistivity of pure GO aerogel and composite aerogels was tested using a resistivity meter. The mechanical properties and wave-absorbing performance of pure GO aerogel and composite aerogels were studied. The results indicate that, compared to pure GO aerogel, the mechanical properties of nano Fe 3 O 4 /GO composite aerogels are basically consistent, both exhibiting good compressive resilience, while the resistivity and wave-absorbing performance of the composite aerogels are significantly improved, with the maximum reflection loss of the 15.0 Fe 3 O 4 /GO aerogel reaching -66.6 dB.
