Electrochromic coatings on plastic substrates

该项目旨在完善可靠的制备方法，制备用于防护眼镜的电致变色涂层，该涂层可以在施加电场时随意改变颜色。所提出的涂层系统将基于通常透明的氧化钨或氧化镍，当用适当的方法着色时，氧化钨或氧化镍可分别呈现深蓝色或深棕色外观。该项目将解决在塑料基底上实现这些无机电致变色涂层的挑战，这些涂层可以表现出高度均匀和快速的着色和漂白过程，适用于眼镜。其目的还在于找到一种更好的替代物，以取代基于氧化铟锡的电致变色器件中常用的透明电极。在本项目中发现的结果最终将用于随后的旨在构建商业电致变色眼镜的完整原型的项目。

The project aims at perfecting reliable fabrication methods for preparing electrochromic coatings for protective eyewear that can change color at will upon the application of an electric field. The proposed coating systems will be based on normally transparent tungsten oxide or nickel oxide that can respectively present a deep blue color or a dark brown appearance when colored with the proper means. The project will address the challenge of achieving these inorganic electrochromic coatings on a plastic substrate that can exhibit highly uniform and rapid coloration and bleaching processes suitable for an eyewear. It also aims at finding a better alternative to the frequently used transparent electrodes in electrochromic devices based on indium tin oxide. Results found in the present project would eventually serve for a subsequent one aiming at constructing a full prototype for a commercial electrochromic eyewear.
