The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project will bring a new family of "structural color" coatings to the commercial marketplace as an alternative to toxic pigments and dyes, as well as a new paradigm for controlling the flow of light. This project aims to improve the energy efficiency of buildings through a coating that can be applied to residential roofing materials during installation or at the original equipment manufacturer level. The technology is a bottoms-up approach to the formation of reflective materials offering significant advantages over state-of-practice cool-roofing alternatives by retrofitting without changing the facade's appearance. The resulting product will rapidly increase adoption of cool-roof technologies due to improved performance without aesthetic loss, a key homeowner concern, leading to substantial energy savings.This Small Business Innovation Research (SBIR) Phase I project addresses key risks and technical challenges associated with commercializing brush block copolymer based photonic crystals. This forms an ideal advanced materials platform for large-area dielectric mirrors due to the low costs of the raw materials and the simplicity of "bottoms-up" fabrication by macromolecular self-assembly. To realize commercial applications, the chemistries for these reflective organic materials need to be optimized for exterior coating applications to resist degradation from natural weathering conditions such as ultraviolet radiation, rain, thermal cycling; furthermore, the formulation must be optimized for standard application. This proposed activity will develop new synthetic routes, stabilization strategies, and the first manufacturing processes to demonstrate these unique advanced materials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小型企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力将为商业市场带来一个新的“结构色”涂料家族，作为有毒颜料和染料的替代品，以及控制光流动的新范式。该项目旨在通过在安装过程中或在原始设备制造商一级应用于住宅屋顶材料的涂层来提高建筑物的能源效率。 该技术是一种自下而上的反射材料形成方法，通过在不改变立面外观的情况下进行改造，与实践中的凉爽屋顶替代方案相比，具有显着优势。由此产生的产品将迅速增加冷却屋顶技术的采用，由于性能的改善，没有美观损失，一个关键的房主关心，导致大量的能源节约。这个小企业创新研究（SBIR）第一阶段项目解决了与商业化刷嵌段共聚物为基础的光子晶体相关的主要风险和技术挑战。 这为大面积介质镜的制备提供了一个理想的先进材料平台，因为它的原材料成本低，并且可以通过大分子自组装进行“自下而上”的制备。为了实现商业应用，这些反射有机材料的化学性质需要针对外部涂层应用进行优化，以抵抗自然气候条件（例如紫外线辐射、雨水、热循环）的降解;此外，必须针对标准应用进行优化。 该计划将开发新的合成路线、稳定策略和第一批生产工艺，以展示这些独特的先进材料。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
