Abstract

The graphene/CoFe2O4/Y3Fe5O12 nanocomposite were successfully synthesized by a deoxidation technique. The phase composition, morphology and electromagnetic properties of the composites were characterized by X-ray diffractometer, scanning electron microscope, X-ray photoelectron spectroscopy, Raman spectra, and vector network analyzer. The electromagnetic parameters of the graphene/CoFe2O4/Y3Fe5O12 nanocomposite were investigated in the 2–18 GHz range. The experimental results show that the graphene/CoFe2O4/Y3Fe5O12 nanocomposite exhibits evidently enhanced microwave absorbing performance in comparison with the CoFe2O4/Y3Fe5O12 nanocomposite. An effective absorption band is obtained by graphene/CoFe2O4/Y3Fe5O12 nanocomposite at 14–16 GHz and the maximum reflection loss is −36.1 dB at 14.88 GHz.
