In this work, reduced graphene oxide (RGO)/ferroferric oxide (RGO/Fe3O4) hybrid composite was successfully fabricated by a facile one-step solvothermal method. The structure, chemical composition, morphology and magnetic properties of the samples were investigated in detail. Fe3O4 microspheres with an average diameter of 250[Formula: see text]nm were uniformly anchored on the surface of the RGO sheets without large aggregation. Moreover, the results demonstrated that the hybrid composite exhibited obviously enhanced microwave absorption properties compared with the pure Fe3O4 microspheres. The minimum reflection loss (RL) of the hybrid composite reached [Formula: see text]36.8[Formula: see text]dB at 17.2[Formula: see text]GHz with a thickness of 5.0[Formula: see text]mm and its effective absorption bandwidth (lower than [Formula: see text]10[Formula: see text]dB) was 3.9[Formula: see text]GHz with a thickness of 2.5[Formula: see text]mm. Significantly, the hybrid composite exhibited a dual-waveband absorption characteristic covering the C and Ku bands. Besides, the relationship between the matching thickness and peak frequency was reasonably explained according to the quarter-wavelength matching theory. Therefore, the obtained composite was a promising candidate for application in microwave absorption.
