Lightweight Chain-Typed Magnetic Fe₃O₄@rGO Composites with Enhanced Microwave-Absorption Properties.

ABSTRACT: A lightweight microwave-absorbing material with a strong electromagnetic-absorption capability of practical significance in the field of electromagnetic compatibility was obtained by adjusting the ratio of Fe₃O₄ and rGO. A nanoparticle material with a chain-typed structure consisting of a combination of Fe₃O₄ and rGO was produced by a hydrothermal method under an applied magnetic field. The electromagnetic loss property of the Fe₃O₄@rGO composites is studied in the frequency range from 2 to 18 GHz. In addition, the reflection loss and the mechanism of microwave absorption are explored. By changing the amounts of rGO, the electromagnetic loss of the Fe₃O₄@rGO composites can be effectively regulated, whic
