Rational Self-Assembly of Fe3O4 Nanostructures on Reduced Graphene Oxide for Enhanced Microwave Absorption

Digital light processing 3D printing of lightweight Fe3O4/rGO/resin composites with enhanced microwave absorption

“…Microwave absorption (MA) materials, with a wide absorption band and strong absorption ability, are promising materials for applications that need to shield and absorb the electromagnetic radiation and interface in undesired bandwidths [2]. Fe3O4 nanoparticles have been widely considered for their high magnetic saturation strength and magnetic loss ability, however, agglomeration in liquids and resins, and poor electrical conductivity greatly constrain its use in further applications [3,4]. To tackle this problem, reduced graphene oxide (rGO) is currently being considered as an alternative choice in combination with Fe3O4 to enhance the electromagnetic MA performance of composites due to its high surface area, high charge carrier mobility, ultra-low density, and excellent electrical conductivity [5][6][7].…”
