This PFI: AIR Technology Translation project focuses on translating atomic layer deposition technology (ALD) to create UV protective thin films onto porous substrates, including nonwoven fiber mats and textiles. Materials used in outdoor protective structures, architectural or decorative elements, and construction are limited by degradation in sunlight or other harsh exposure. The ALD technology is a unique approach to create ultra-thin and ultra-conformal coating layers onto polymer fibers with complex geometries. These coatings have the capacity to protect the underlying polymer from damaging ultraviolet exposure from the sun or other light sources. The coatings can compete with relatively expensive solution-dyed acrylic materials that now dominate the outdoor textile market. The coating can work with a range of material substrates beyond those currently used. Technology implementation requires new knowledge of process scaling and reactor design challenges. The project accomplishes this goal by exploring a unique "flow-through" reactor design prototype resulting in a demonstration vehicle to evaluate materials and process throughput capabilities to meet market demands. The project engages VaporPulse Technologies to provide guidance in the field of coatings on fibers as well as expertise in project commercialization and marketing as they pertain to the potential to translate the science/technology along a path that may result in a competitive commercial reality. The technology could have commercial impact well beyond UV protection. Other fiber systems that can benefit from improved coatings include filtration and separations media, personal protective equipment, electronic and medical textiles, or engineered fibers or fabrics for military personnel. In the long term, society will benefit by having materials and products that provide safe and reliable operation under harsh and variable outdoor conditions for longer times at lower cost. The work will also have long-term impact by expanding foundational understanding of thin film reaction science and engineering with impact in many other future fields. This project will also help educate a PhD student in Chemical Engineering to learn the challenges of technology translation from a lab to a small business, allowing those skills to be expanded and passed on in the future.

该PFI：AIR技术转化项目的重点是转化原子层沉积技术（ALD），以在多孔基材（包括非织造纤维垫和纺织品）上制造紫外线防护薄膜。 用于户外防护结构、建筑或装饰元件以及建筑的材料受到阳光或其他恶劣暴露条件下降解的限制。 ALD技术是在具有复杂几何形状的聚合物纤维上形成超薄和超保形涂层的独特方法。 这些涂层具有保护下面的聚合物免受来自太阳或其他光源的紫外线暴露的损害的能力。 该涂料可以与目前主导户外纺织品市场的相对昂贵的溶液染色丙烯酸材料竞争。 该涂层可以与目前使用的材料基底之外的一系列材料基底一起工作。 技术的实施需要对工艺规模和反应器设计挑战有新的认识。该项目通过探索独特的“流通”反应器设计原型来实现这一目标，从而产生一辆演示车来评估材料和工艺吞吐量能力以满足市场需求。 该项目聘请VaporPulse Technologies在纤维涂层领域提供指导，并在项目商业化和营销方面提供专业知识，因为它们涉及到将科学/技术沿着一条可能导致竞争性商业现实的道路转化的潜力。 该技术的商业影响可能远远超出紫外线防护。可受益于改进涂层的其他纤维系统包括过滤和分离介质、个人防护设备、电子和医用纺织品或用于军事人员的工程纤维或织物。从长远来看，社会将受益于材料和产品，在恶劣和多变的户外条件下以较低的成本提供更长时间的安全可靠运行。 这项工作还将通过扩大对薄膜反应科学和工程的基础理解，对许多其他未来领域产生影响，从而产生长期影响。该项目还将帮助教育化学工程博士生学习从实验室到小企业的技术翻译的挑战，使这些技能在未来得到扩展和传承。
