航空聚碳酸酯透明件表面导电/防护功能多层膜结构匹配机理研究

Transparent conducting films and anti-scratch organic coatings are predominant topcoat used on transparent substrate to meet the requirements of anti-radar and flying in poor environments in the aeronautical industry, which require higher quality to the preparation and matching of organic coatings and conducting films. To address the current issues, such as delaminating cracking and poor adhesion during aging tests, we will investigate the electrical and environment conditioning properties of the multilayer films (primer layer/ conductive film/protective coating) to improve the adhesion and aging properties. The adhesion and electrical behaviors of the amorphous transparent indium zinc oxide (IZO) under aging could be studied and tuned by interfacial matching and exhibited by selecting different kinds of coatings, silicone and polyurethane coatings, et al among the multilayer films, based on the existing investigation of single layer in conductive multilayer films.

为满足高性能航空透明件的雷达波隐身以及耐极端飞行环境的需求，需要在透明件表面进行透明导电薄膜的镀制以及防护涂层的涂敷，这对无机导电薄膜/有机防护涂层复合多层膜的制备和匹配提出了极高的要求。本项目针对透明件表面功能膜层在环境试验中由于结构不匹配导致的易开裂、附着性变差等关键技术问题，以新型航空聚碳酸酯透明件表面多层膜体系（底涂层/导电薄膜/防护面涂层）为研究对象，以膜层电学特征和环境稳定性为研究重点，以期改善膜层附着力以及使用长效性。基于申请者以往防护涂层和导电薄膜单层膜研究基础，采用逐层分析方法，开展有机硅和聚氨酯力学性能不同的涂层材料对氧化铟锌（IZO）导电薄膜环境稳定性的影响研究，获得底涂层和面涂层相互作用下多层膜结构对导电薄膜附着以及电学特征的调控和影响机制。
