Abstract

High efficient MIL-53(Fe) derived γ-Fe₂O₃ coated by carbon framework (MCC for short) and compound with reduced graphene oxide for broadband microwave absorption is prepared by facile hydrothermal method and gradient temperature calcination. The sheets/bowknot-shaped nanoparticles structure have better microwave absorption performance via uniting magnetic γ-Fe₂O₃ core, carbon skeleton and rGO sheets. Binary material calcined at 600°C has an optimal R_L value −62.53dB under 2.66mm thickness. In addition, the ternary MCC/rGO of 700°C calcination has better performance with an 11.68GHz effective absorption bandwidth (from 6.32GHz to 18GHz) of a single thickness of 3.60mm, and a maximum R_L of −43.13dB at 3.25mm thickness. The MOF framework enhances particle stability and internal scattering, while graphene provides a larger absorption surface, coupled with the good impedance matching rooted in suitable permittivity and permeability, the material is an ideal new type of absorbing material.
