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

这项小型企业技术转移研究(STTR)第一阶段计划将包括革命性的离子自组装单分子层(ISAM)方法，即逐层创建多功能薄膜，以生产自组装、电子和光活性聚合物薄膜。F&Amp；S/露娜的创新和研究伙伴已经证明，离子自组装技术既可以用于制备聚合物发光二极管，也可以用于制备本质上非中心对称的电光聚合物薄膜。由于自组装技术本身依赖于聚电解质，电致变色器件成为ISAM与导电聚合物结合的另一个重要机会领域。当施加电压时，这样的器件改变它们的颜色和/或不透明度。ISAM工艺允许对电致变色器件的层状结构的组装进行分子水平的控制，具有特殊的均质性和易于加工。ISAM电致变色薄膜器件具有增强电致变色对比度和提高开关速度的潜力，以及优异的均匀性、高热稳定性和化学稳定性、简单和低成本等主要优势。重要的是，这种薄膜可以在柔性衬底上大面积共形制造。F&A；S/露娜创新公司将与光电子和聚合物合成大学的研究人员合作，将最新的实验室成果快速转化为原型设备产品。ISAM电致变色设备立即应用于军事和商业领域，用于廉价、大面积、柔性光学显示器、智能窗户和汽车后视镜和天窗。

This Small Business Technology Transfer Research (STTR) Phase I program will encompass the revolutionary ionically self-assembled monolayer (ISAM) methods of creating multifunctional thin-films monolayer by monolayer to yield self-assembled, electronically and photonically-active polymeric thin films. F&S/Luna Innovations and research partners have demonstrated that the ISAM technique can be used to fabricate both polymer light emitting diodes and inherently noncentrosymmetric electro-optic polymer films. Because the self-assembly technique relies inherently on polyelectrolytes, electrochromic devices become another important area of opportunity for the combination of ISAM with conducting polymers. Such devices change their color and/or opacity when a voltage is applied. The ISAM process allows molecular level control over the assembly of the layered structures of an electrochromic device with exceptional homogeneity and ease of processing. ISAM electrochromic thin film devices offer the potential for enhanced electrochromic contrast and increased switching speed as well as major advantages of excellent homogeneity, high thermal and chemical stability, simplicity and low-cost. Importantly, the films can be conformally fabricated over large areas on flexible substrates. F&S/Luna Innovations will work with optoelectronic and polymer synthesis university researchers to rapidly transition recent laboratory results to prototype device products.ISAM electrochromic devices have immediate application in military and commercial areas for inexpensive, large area, flexible optical displays, smart windows, and automotive rear view mirrors and sunroofs.
