STTR Phase II: Electrochromic Devices Fabricated from Self-Assembled Polyelectrolytes for Flat Panel Displays

这个小型企业技术转移(STTR)第二阶段项目将继续开发一种基于有机纳米材料自组装的新电致变色设备。第一阶段使用这些材料制造实验室规模的设备。对纳米级材料成分的精确控制，加上沉积的薄层(40纳米厚)，首次实现了25-50毫秒的开关速度，这几乎足以满足显示应用的需要。此外，还发现这些在固态中制造的材料只需施加1.0V就可以进行开关。第二阶段将专注于优化设备性能，开发三态和多色设备，并在商业产品开发所需的环境条件下评估性能。这项技术的市场非常大，范围从汽车自动调光后视镜到住宅和商业建筑的智能窗户、智能眼镜和显示产品。第三阶段计划扩大制造规模，并将在行业伙伴关系中进行。

This Small Business Technology Transfer (STTR) Phase II project will continue development of a new electrochromic device based on self-assembly of organic nanomaterials. Phase I used these materials to create laboratory scale devices. Precise control of the material composition at the nanometer (nm) scale, combined with the thin layers deposited (40 nm thick), allowed switching speeds of 25-50 milliseconds for the first time, which are nearly fast enough for display applications. Further, it was found that these materials, fabricated in the solid state, could be switched by applying only 1.0 volt. Phase II will focus on optimizing device performance, developing tri-state and multi-color devices, and evaluating performance under environmental conditions necessary for commercial product development. Markets for the technology are very large and range from automotive self-dimming rear-view mirrors to smart windows for residential and commercial buildings, smart glasses, and display products. Phase III is planned for manufacturing scale-up and will be conducted in an industrial partnership.
