摘要
With the quick evolution of information technology, it is necessary to develop high-performance microwave absorbers to attenuate electromagnetic waves. Herein, we prepared graphene-BN-Fe3O4 composites by a facile solvothermal method using graphene as the dielectric loss component, Fe3O4 as the magnetic loss component and BN as the dielectric modulating component. BN and graphene form a 2D/2D structure adhered with Fe3O4. When the ratio of BN to graphene is 1:1 with Fe3O4 content of 60 %, the absorber exhibits excellent electromagnetic wave absorption performance. A RLmin of -42.31 dB is obtained with an effective band of 4.5 GHz at 1.04 mm, while the maximum EAB of samples can reach 4.59 GHz (13.41-18 GHz) with a RLmin value of -33.16 dB at 1.05 mm. The prepared composite exhibits a wide absorption band at a thin thickness. Enhanced microwave absorption performance is achieved mainly due to the synergistic effect of increased interface polarization loss, appropriate conductive loss, and improved impedance matching.
