Preparation and Microwave Absorption Mechanism of Graphene/Zinc Ferrite and Nickel Ferrite Composite Absorbers
This study reports the hydrothermal synthesis of graphene/zinc ferrite and graphene/nickel ferrite composites, demonstrating that the graphene/zinc ferrite (1:2) variant achieves superior microwave absorption performance (−28.3 dB at 17.2 GHz) through synergistic dielectric and magnetic losses, offering a rational design strategy for high-performance electromagnetic wave absorbers.
