This Small Business Innovation Research (SBIR) Phase I project aims to develop transparent electrodes based on silver nanowires and polymer substrates to replace indium tin oxide for applications in thin-film and flexible electronic devices. The approach is to form a silver nanowire-polymer composite with sheet resistance and transmission comparable to indium tin oxide coated on glass. A transfer technique will be employed to produce smooth electrode surface free of protruding silver nanowires. The expected outcome of the project is a new transparent electrode technology, with less than 10 nm surface roughness, 85% transmission, and 10 ohm per square sheet resistance. The project will also demonstrate high-performance thin-film electronic devices based on the composite electrodes. The broader/commercial impact of this project will be the potential to provide a viable alternative to indium tin oxide to reduce the production cost of important electronic devices such as organic light emitting diodes, thin-film solar cells, and liquid crystal displays. The combined markets for these devices represent a substantial growth opportunity in the near future. However, the rising cost of indium and the lack of flexibility of indium tin oxide have become a major challenge. In this project, new composite electrodes will be developed, which are anticipated to be low cost, flexible and even stretchable without compromising device performance.

这项小型企业创新研究（SBIR）I期项目旨在根据银纳米线和聚合物底物开发透明的电极，以取代用于薄膜和柔性电子设备的应用中的二锡氧化物。该方法是形成一个银色纳米线 - 聚合物复合材料，具有薄板电阻和透射率，可与玻璃上涂层的氧化二锡氧化物相当。将采用一种传输技术来产生光滑的电极表面，而没有突出的银纳米线。该项目的预期结果是一种新的透明电极技术，其表面粗糙度少于10 nm，每平方板电阻为85％和10欧姆。 该项目还将根据复合电极展示高性能薄膜电子设备。 该项目的更广泛/商业影响将是提供氧化二锡锡的可行替代品，以降低重要电子设备的生产成本，例如有机光发射二极管，薄膜太阳能电池和液晶显示。这些设备的合并市场在不久的将来代表了大量增长机会。但是，依赖的成本上升和缺乏氧化酰化锡的灵活性已成为一个重大挑战。在这个项目中，将开发新的复合电极，预计不会在设备性能损害设备性能的情况下进行较低的成本，灵活甚至可以拉伸。
