MIL-100(Fe) decorated on graphene using as wideband microwave absorption material

Abstract

Microwave absorption materials have attracted significant attention because of potential application in military stealth and information safety. In this work, MIL-100(Fe)/Graphene composite was successfully synthesized by a facile method and the microwave absorption mechanism were studied systematically. The as-prepared MIL-100(Fe)/Graphene shows excellent microwave absorption properties with a minimum reflection loss value of -50.9 dB at 13.6 GHz for absorber thickness of 1.8 mm. Moreover, the absorption peak frequency and effective microwave absorption region (< -10 dB) can be controlled in the range of 3.6-18.0 GHz by varying the thickness of the absorber. The highly efficient electromagnetic absorption performance of the MIL-100(Fe)/Graphene is mainly attributed to the enhanced impedance matching. The MIL-100(Fe)/Graphene composite has a great potential applied in the field of microwave absorption.
