Abstract

With the development in communication technology, severe electromagnetic wave radiation pollution has been created, resulting in electromagnetic interference and health hazards. Thus, materials with excellent microwave absorbing properties have become an urgent need. Magnetic particles with core-shell structures are widely used as microwave absorbers due to their high magnetic loss, little eddy current effect, and tunable dielectric properties. Herein, carbonized Metal-Organic Framework (MOF), and Graphene Oxide (GO) are used to coat the Y2Fe16Si (YFeSi) magnetic powders to form YFeSi@MOF and YFeSi@GO core-shell structures. Their microwave absorption properties are studied. The reflection loss (RL) of YFeSi@MOF can reach -19.2dB@15.1GHz under 1.4 mm thickness with an effective bandwidth of 4.7 GHz, and the reflection loss of YFeSi@GO can reach -18.3dB@16.2GHz under 1.6 mm thickness with an effective bandwidth of 3.9 GHz.
