The microwave absorption properties of Y2Fe16Si@MOF and Y2Fe16Si@GO composites

With the development in communication technology, severe electromagnetic wave radiation pollution has been created, resulting interference and health hazards. Thus, materials with excellent microwave absorbing properties have become an urgent need. Magnetic particles core-shell structures are widely used as absorbers due to their high magnetic loss, little eddy current effect, tunable dielectric properties. Herein, carbonized Metal-Organic Framework (MOF), Graphene Oxide (GO) coat Y2Fe16Si (YFeSi) powders form YFeSi@MOF YFeSi@GO structures. Their absorption studied. The reflection loss (RL) of can reach [email protected] under 1.4 mm thickness effective bandwidth 4.7 GHz, [email protected] 1.6 3.9 GHz.
