Novel Fe3O4@SiO2@RGO nanocomposites were fabricated and the nanocomposites which were embedded into paraffin wax with low filler content (20 wt%) showed excellent microwave absorption properties. The minimum reflection loss can reach -26.6 dB at 9.7 GHz, and the reflection loss was less than -10 dB in the frequency range from 4.4 to 17.3 GHz with an absorber thickness of 2.0-5.0 mm. Compared with the pure Fe3O4 and Fe3O4@SiO2, the Fe3O4@SiO2@RGO nanocomposites exhibited superior absorption properties. The mechanism of enhanced wave absorption properties was explained.
