A new class microwave absorption coating based on assemblies of core-shell magnetic nanoparticles was facile preparation to improve absorption bandwidth and durability. The microwave absorption coating with a thickness of ca.1.5mm exhibited a wide bandwidth (ca.9.2GHz). Furthermore, the durability of microwave absorption coating was further evaluated. It showed good water-shedding ability and mechanical stability. The excellent performance was mainly attributed to special surface rough structure and low surface energy of coating, resulting from assemblies of core-shell magnetic nanoparticles. These provide a new idea to design and preparation of microwave absorption coating with high performance for application in stealth technology.
