英文摘要	Expanded graphite/polyaniline (EG/PANI) composites were synthesized by in. situ polymerization, and EG/PANI/Fe3O4 composites were obtained by adsorbing Fe3O4 nanoparticles on the surface of EG/PANI composites. The surface morphologies, phase structures and microwave absorption properties were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR), and vector network analyzer (VNA). The results showed that when the HCl concentration was 0.05 mol/L, the RLmin reached -37 dB at 8.64 GHz with the thickness of d = 2 mm. With the increase of doping concentration, the minimum reflection loss peak moved to low frequency, and the matching thickness became thicker. The dielectric relaxation polarization, eddy current loss and interference cancellation phenomenon of lambda/4 model played the important role in the process of absorption. The double peaks made EG/PANI/Fe3O4 composites possible in the microwave absorption.
