The broader impact/commercial potential of this Small Business Innovation Research Phase I project will be the development of an effective approach to energy reduction in residential and commercial settings using film materials on building windows. Windows coated with passive solar film created in this project will help limit the amount of infrared and ultraviolet light entering a building. This lowers the amount of heat accumulating within the building and reduces the need for air conditioning. Importantly, this approach can be used in both new buildings and old buildings. The proposed materials can yield up to 50% energy savings for air conditioning. The novel process used in this project enhances the thermal stability of cyanine dyes up to 300 degrees Celsius, allowing for incorporation of the these dyes into inks, polymer pellets and films with protection from thermal degradation. This thermal stability would allow the nanomaterial to be incorporated into high-density polymers such as polycarbonates, polyimides and Teflon, which would allow use of inexpensive dyes to take advantage of the enhanced polymer structural stability for versatile and durable applications. The dyes are significantly less expensive than the porphyrin dyes or sputter-coated Indium-Tin oxide-Silver-Gold materials, and are potentially simpler to process into functional products for passive solar applications. The technical objectives of this Phase I research project are to develop low-cost, thermally stabilized organic dyes to absorb specific wavelengths of ultraviolet and near-infrared for passive solar application on windows in commercial and residential facilities. This will be accomplished by adding a functional group at the end of an organic dye chain of carbon groups in order to strategically bind the dyes to a metal oxide nanoparticle. The chemical functional groups reside on side chains that are easily modified by simple chemical reactions, and the change has no effect on the chromophore so the dyes? ability to filter specific wavelengths of light are not disturbed. This has been demonstrated with several model dye compounds with various binding chemical functional groups. These modifications thermally stabilize organic dyes so they can survive high polymer extrusion temperatures without the need for hazardous organic solvents. The research objectives include the incorporation of dye bound to ZnO nanoparticles into polymers through melt extrusion; development and modification of dyes to absorb in specified wavelength ranges; binding of model dye(s) to ZnO nanoparticles and determination of optical and thermal stability; and scaling up the electrochemical process.

这个小企业创新研究第一阶段项目的更广泛的影响/商业潜力将是开发一种有效的方法，在住宅和商业环境中使用建筑窗户上的薄膜材料来减少能源。在这个项目中创建的涂有被动太阳膜的窗户将有助于限制进入建筑物的红外线和紫外线的数量。这降低了建筑物内积聚的热量，并减少了对空调的需求。重要的是，这种方法可以用于新建筑和旧建筑。所提出的材料可以为空调节省高达50%的能源。该项目中使用的新工艺提高了花青染料的热稳定性高达300摄氏度，允许将这些染料掺入油墨，聚合物颗粒和薄膜中，防止热降解。这种热稳定性将允许纳米材料掺入高密度聚合物如聚碳酸酯、聚酰亚胺和特氟隆中，这将允许使用廉价的染料以利用增强的聚合物结构稳定性用于多用途和耐用的应用。这些染料比卟啉染料或涂覆有荧光剂的铟锡氧化物-银-金材料便宜得多，并且可能更容易加工成用于被动太阳能应用的功能产品。该第一阶段研究项目的技术目标是开发低成本、热稳定的有机染料，以吸收特定波长的紫外线和近红外线，用于商业和住宅设施窗户上的被动太阳能应用。这将通过在碳基团的有机染料链的末端添加官能团来实现，以便策略性地将染料结合到金属氧化物纳米颗粒。化学官能团位于侧链上，这些侧链很容易通过简单的化学反应进行修饰，这种变化对发色团没有影响，所以染料？过滤特定波长的光的能力不受干扰。这已经用具有各种结合化学官能团的几种模型染料化合物证明。这些改性使有机染料热稳定，因此它们可以在高聚合物挤出温度下存活，而不需要危险的有机溶剂。研究目标包括通过熔融挤出将染料结合到ZnO纳米颗粒中;开发和改性染料以吸收特定波长范围;将模型染料结合到ZnO纳米颗粒并测定光学和热稳定性;以及扩大电化学过程。
