项目摘要

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.

这个小企业技术转移研究（STTR）第一阶段计划将包括革命性的离子自组装单层（ISAM）方法，通过单层创建多功能薄膜，以产生自组装，电子和光子活性聚合物薄膜。 FS/Luna Innovations和研究合作伙伴已经证明，ISAM技术可用于制造聚合物发光二极管和固有非中心对称电光聚合物薄膜。由于自组装技术固有地依赖于聚电解质，电致变色器件成为ISAM与导电聚合物组合的另一个重要机会领域。当施加电压时，这样的装置改变它们的颜色和/或不透明度。 ISAM工艺允许对电致变色装置的分层结构的组装进行分子水平控制，具有优异的均匀性和易于加工性。ISAM电致变色薄膜器件提供了增强的电致变色对比度和增加的切换速度的潜力，以及优异的均匀性、高热稳定性和化学稳定性、简单性和低成本的主要优点。重要的是，膜可以在柔性基底上的大面积上共形地制造。 F S/Luna Innovations将与光电和聚合物合成大学的研究人员合作，将最新的实验室结果快速转化为原型器件产品。ISAM电致变色器件可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，智能窗户以及汽车后视镜和天窗。
