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

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.
