【摘要】：作为解决电磁污染问题与实现装备战场隐身的有效手段,吸波涂层材料具有广泛的应用前景。碳系材料因其广泛的来源、简单的制备工艺、低密度、高导电率等优点,在吸波涂层材料领域受到国内外研究人员的高度重视。对吸波涂层材料的损耗机制进行了叙述,介绍了电阻型损耗、电介质型损耗以及磁损耗三种损耗机制中电磁波的损耗和吸收原理。综述了碳纤维、碳纳米管、石墨烯等新型碳系材料的特性及其在吸波涂层材料领域的研究现状。对碳纤维进行活化处理或使用多孔碳纤维、螺旋碳纤维等代替普通碳纤维能够有效提高其吸波性能。碳纳米管具有多种结构,其中阵列状多壁碳纳米管吸波性能最佳,采用一些具备磁损耗的材料与碳纳米管进行共混、包覆或填充处理是目前的主要研究方向。石墨烯几乎没有磁损耗,单独使用时,阻抗匹配较差,影响其吸波性能的发挥,通常将石墨烯与磁损耗型材料复合,改善材料的阻抗匹配,提高吸波效果。最后,根据碳系吸波涂层材料的研究现状,对其未来的发展方向进行了展望。
[Abstract]:As an effective means to solve electromagnetic pollution and achieve battlefield stealth, microwave absorbing coating materials have a wide application prospect. Carbon materials have many advantages such as wide source, simple preparation process, low density, high conductivity and so on. In the field of absorbing coating materials, researchers at home and abroad attach great importance to it. The loss mechanism of absorbing coating materials is described, and the resistance loss is introduced. The loss and absorption principle of electromagnetic wave in three loss mechanisms of dielectric loss and magnetic loss. The carbon fiber, carbon nanotubes, carbon nanotubes, carbon nanotubes, carbon fibers, carbon nanotubes, carbon nanotubes, carbon nanotubes, The characteristics of new carbon materials such as graphene and their research status in the field of microwave absorbing coating materials. Carbon nanotubes (CNTs) have a variety of structures, among which arrayed multi-walled carbon nanotubes (MWNTs) have the best absorbing properties. Some materials with magnetic loss are used to blend with carbon nanotubes (CNTs). The coating or filling treatment is the main research direction at present. Graphene has little magnetic loss. When used alone, the impedance matching is poor, which affects the display of its absorbing property, and usually the graphene is combined with the magnetic loss type material. Finally, according to the research status of carbon system absorbing coating materials, the future development direction is prospected.
