Three dimensional flower like ZnFe2O4 ferrite loaded graphene: Enhancing microwave absorption performance by constructing microcircuits

In the research of new type of absorbing materials, the influence of special three-dimensional (3D) microstructure and the composite effect of multi-component materials on the electromagnetic properties and absorbing properties of materials has attracted widespread attention. In this work, the 3D flower like ZnFe2O4 ferrite (3D-ZFO) was prepared by two solution chemical precipitation processes, and then a simple ultrasonic and heat treatment...
