The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project will be to advance the development of a self-cleaning coating technology for applications in household products, automotive, sensors and aerospace. Fluorinated materials have been widely used in self-cleaning applications due to their excellent wear characteristics, and super-hydrophobicity, but their environmental impact motivates new solutions. Attempts to date have typically resulted in materials that are cloudy, non-durable and/or too expensive for commercial relevance. This project will advance a new coating that adheres well to substrates, offers high abrasion resistance similar to glass, and exceptional weather resistance. This Small Business Innovation Research (SBIR) Phase I project will allow the advancement of a durable, non-fluorinated, super omniphobic, optically clear coatings for industrial applications. The proposed work is focused on enhancing the performance of nonfluorinated omniphobic coatings in three specific ways. First, the adhesion of omniphobic coatings will be improved such that they will be able to withstand submersion in water for months without showing swelling/delamination. This will be achieved by using water stable urethane polymers and/or prior surface treatment of the substrate. Second, the abrasion resistance of the coating will be enhanced by using a combination of urethane precursors and fillers. Finally, the weatherability will be increased by using UV stabilizers along with UV stable urethane polymers such that the coatings will have improved performance in outdoor applications.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/商业潜力将是推动自清洁涂层技术的发展，用于家用产品，汽车，传感器和航空航天。氟化材料因其优异的磨损特性和超疏水性而广泛用于自清洁应用，但其对环境的影响促使人们提出新的解决方案。 迄今为止的尝试通常导致材料浑浊、不耐用和/或对于商业相关性来说太昂贵。该项目将推进一种新的涂层，该涂层能够很好地附着在基材上，提供类似于玻璃的高耐磨性和优异的耐候性。这个小企业创新研究（SBIR）第一阶段项目将允许一个持久的，非氟，超全憎性，光学透明涂料的工业应用的进步。拟议的工作是集中在提高性能的非氟全憎涂料在三个具体的方式。首先，全憎性涂层的粘附性将得到改善，使得它们将能够承受数月的水中浸没而不显示出溶胀/分层。这将通过使用水稳定的氨基甲酸酯聚合物和/或基底的预先表面处理来实现。第二，通过使用聚氨酯前体和填料的组合将增强涂层的耐磨性。最后，耐候性将通过使用紫外线稳定剂沿着紫外线稳定聚氨酯聚合物来提高，从而使涂料在户外应用中具有更好的性能。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。
