Abstract 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.

基于磁性纳米粒子组件的微波吸收涂层可提高吸收带宽和耐久性

摘要 一种基于核壳磁性纳米粒子组装体的新型微波吸收涂层可以很容易地制备，以提高吸收带宽和耐久性。厚度约1.5mm的微波吸收涂层表现出较宽的带宽（约9.2GHz）。此外，进一步评估了微波吸收涂层的耐久性。它表现出良好的分水能力和机械稳定性。优异的性能主要归功于特殊的表面粗糙结构和低表面能的涂层，这是由于核壳磁性纳米粒子的组装所致。这些为设计和制备用于隐身技术的高性能微波吸收涂层提供了新的思路。
