This Discovery program will explore a new methodology using bio-based solvents to make ordered polymer nanostructures suitable for light harvesting using gas-expanded liquids (GXL). A renaissance is underway for additive manufacturing, such as 3D printing and rapid prototyping. However, current approaches are far too slow and do not provide the high performance material properties required for emerging applications in light/energy harvesting. For these high performance light harvesting coatings and devices, including photovoltaic encapsulants and anodes, photocatalytic coatings and greenhouse films; new nanoparticles (NPs) using earth abundant and friendly elements and a new way to control their assembly into ordered structures is required. Currently, multi-step complex chemistries are required to form NPs, stabilize them, then attach them to surfaces to form 3D ordered structures, with a poor ability to control surface topology. In these approaches, a solvent is normally required in the various reaction/processing steps to facilitate NP dispersion and deposition. However, current solvents are considered VOCs, which are becoming increasingly regulated for industrial use, while also they provide no functionality and give very poor control of the NP self-assembly process and deposition.

该发现程序将使用基于生物的溶剂探索一种新方法，以制造有序的聚合物纳米结构，适合使用气体膨胀液体（GXL）进行轻度收集。增材制造正在进行复兴，例如3D打印和快速原型制作。但是，当前的方法太慢了，并且无法提供光/能量收集中新兴应用所需的高性能材料特性。对于这些高性能收集涂料和设备，包括光伏封装和阳极，光催化涂料和温室膜；需要新的纳米颗粒（NPS）使用地球丰富而友好的元素，以及一种将其组装控制成有序结构的新方法。当前，需要多步复杂的化学物质才能形成NP，稳定它们，然后将它们连接到表面以形成3D有序结构，无法控制表面拓扑的能力。在这些方法中，通常需要在各种反应/加工步骤中需要溶剂，以促进NP分散和沉积。但是，当前的溶剂被认为是VOC，这些溶剂正受到工业用途的越来越多的监管，同时也没有提供任何功能，并且对NP自组装过程和沉积的控制也很差。
