SBIR Phase I: Printable Conducting Polymers for Polymeric Electronic Circuits

这个小型企业创新研究(SBIR)第一阶段项目将开发可印刷的、可溶的导电聚合物，可以使用紫外光进行交联。这些可印刷的导电聚合物可以使用光刻技术印刷成具有2维特征的薄膜，从用于柔性显示器的固体薄膜到用于印刷线路板和多芯片模块的高度详细的特征。这些印刷导电聚合物还将比无机电子产品更低、更灵活、更轻、机械更坚固。可溶性导电聚合物将通过紫外光诱导的聚合反应合成具有交联性的官能团。薄膜将被浇铸在衬底上，然后在紫外光下通过交联聚合变得不溶。将测量和优化光聚合动力学，以最大限度地提高微米级导电特性的光成像分辨率。我们将进行工程分析，以确定我们建议的导电聚合物的工艺条件、印刷分辨率和导电性是否对电子应用具有商业吸引力。可印刷导电聚合物的商业应用包括柔性显示器、印刷线路板、多芯片模块、晶体管和发光二极管，特别是当导电性和塑料的性能(弹性、机械稳定性等)相结合时。都是我们想要的。

This Small Business Innovation Research (SBIR) Phase I project will develop printable, soluble conducting polymers that can be crosslinked using ultra violet light. These printable, conducting polymers can be printed using photolithography into thin films with 2-dimensional features ranging from solid thin films for flexible displays to highly detailed features for printed wiring boards and multi chip modules. These printed conducting polymers will also be low-cost, flexible, lightweight and mechanically more robust than inorganic electronics. Soluble, conductive polymers will be synthesized with functional groups that can be crosslinked by a polymerization reaction induced by ultraviolet light. Thin films will be cast onto substrates and then rendered insoluble by the crosslinking polymerization under ultra violet light. The kinetics of photopolymerization will be measured and optimized to maximize the resolution of photoimaging for micron sized conducting features. An engineering analysis will be performed to determine if the process conditions, printing resolution and conductivity of our proposed conducting polymers is commercially attractive for electronics applications.Commercial applications for printable conducting polymers include flexible displays, printed wiring boards, multi chip modules, transistors, and light emitting diodes especially when the combination of conductivity and the properties of plastics (flexibility, mechanical stability, etc.) are desired.
