多频谱隐身涂层材料研究进展

摘要

With the development of military stealth technology and the EMC/EMI technology in the internet of things , stealth coating material has attracted more and more attention , as an important branch of functional material .During recent years, stealth coating material has achieved promising improvement from either the material category , design or synthesis point of view, by the promotion of application requirement and technical innovation .Radar absorbing coating, infrared low emissivity coating and multispectral stealth-compatible coating are three most widely developed stealth coatings concerned in this review.Combing recent advances with our previous works , stealth mechanisms, material characteristics and appli-cation techniques were introduced .The promotion effect of novel materials and design approaches on stealth materials was shown, e.g.anisotropic magnetic/dielectric materials, nanostructure dynamic magnetism, and compositing techniques. At last, the problems and future trends of mutispectral stealth coating material were proposed based on the analysis of pres-ented researches.%随着军事隐身技术以及民用物联网电磁兼容、抗电磁干扰技术的发展，隐身涂层材料的重要性日益受到社会关注，该类材料逐渐成为功能材料的一个重要分支。近年来，在需求牵引和技术革新的带动下，隐身涂层材料从材料体系、设计方法到制备技术都取得了很大的进展。结合国内外最新发展动态和中心开展的主要工作，介绍了当前广泛发展的雷达吸波涂层、红外低发射率涂层以及多频谱兼容隐身涂层这3类涂层的隐身机理、材料特性以及应用技术方面的研究进展；重点关注先进材料体系和设计方法对隐身涂层材料的牵引，包括各向异性磁性材料/介电材料、纳米结构动态磁化理论以及材料复合技术等；最后通过对各种材料技术的分析，提出多频谱隐身涂层材料发展所面临的问题，分析了该领域未来发展的趋势。
