The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is that the silica membrane products will enable low-cost production of hydrogen gas, (H2, a clean energy carrier), and carbon dioxide (CO2, a greenhouse gas) capture for utilization or storage on a large scale - economically mitigating CO2 emissions to the environment. Specifically, the program will bring the technology beyond the laboratory by demonstrating scalability of membrane production using conventional processes and capitalizing on the long-term stability of the membranes when used with realistic gas streams. The team seeks to license the technology to a membrane manufacturer and developer, which can then conduct pilot-scale field tests of the membrane systems and offer small commercial systems for separation and purification of H2 from various industrial streams. The students participating in this program will benefit from interdisciplinary training on membranes and separation, H2 purification and carbon capture, materials science and engineering, and advanced manufacturing. The research will become a valuable vehicle to attract students from underrepresented groups at various levels (graduate, undergraduate, and high school) to experience entrepreneurial multi-disciplinary research and inspire them to pursue STEM careers and entrepreneurship.The project aims to demonstrate the potential of polymeric organosilica (POSi) membranes by meeting three milestones. (1) Prepare membranes with 50% higher H2 permeance and three times higher H2/CO2 selectivity than current commercial membranes by optimizing polymer precursors and fabrication conditions; (2) Scale-up membrane production (10 – 100 m2 membrane area) using industrial roll-to-roll facilities; and (3) Demonstrate continuous long-term (2-4 weeks) performance and stability with simulated gas mixtures. The key innovation of the technology is a facile means of preparing an ultrathin layer (10 nm or less) of inorganic material on top of polymeric membranes, providing superior H2 permeance and H2/CO2 selectivity. Such polymeric membranes are routinely produced in industry, and they provide excellent mechanical support for the ultrathin inorganic selective layer during processing and use. the team's approach represents a new, scalable, reproducible, and low-cost means of preparing inorganic membranes for gas separation, in contrast to the high cost and poor scalability of existing production routes, which have prevented the adoption of high-performance inorganic membranes for gas separation.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.

该创新合作伙伴关系 - 技术转化 (PFI-TT) 项目更广泛的影响/商业潜力在于，二氧化硅膜产品将能够低成本生产氢气（H2，一种清洁能源载体）和二氧化碳（CO2） （一种温室气体）捕获并大规模利用或储存——经济地减少二氧化碳对环境的排放。具体来说，该计划将通过展示使用传统工艺的膜生产的可扩展性并利用长期优势，使该技术超越实验室。的稳定性该团队寻求将该技术授权给膜制造商和开发商，然后他们可以对膜系统进行中试规模的现场测试，并提供用于从各种工业中分离和纯化氢气的小型商业系统。参与该项目的学生将受益于膜和分离、氢气纯化和碳捕获、材料科学与工程以及先进制造的跨学科培训，该研究将成为吸引来自各个级别的代表性不足群体的学生的宝贵工具。研究生、本科生、高中）体验创业型多学科研究，并激励他们追求 STEM 职业和创业精神。该项目旨在通过实现三个里程碑来展示聚合有机硅 (POSi) 膜的潜力 (1) 制备氢气渗透率提高 50% 和三倍的膜。通过优化聚合物前体和制造条件，比目前的商业膜具有更高的 H2/CO2 选择性；(2) 使用工业卷对卷扩大膜生产（10 – 100 m2 膜面积）； (3) 通过模拟气体混合物展示连续的长期（2-4 周）性能和稳定性 该技术的关键创新是在无机材料上制备超薄层（10 nm 或更小）的简便方法。聚合物膜的顶部，提供优异的 H2 渗透性和 H2/CO2 选择性。此类聚合物膜通常在工业中生产，并且在加工和使用过程中为超薄无机选择性层提供出色的机械支撑。该团队的方法代表了一种新的、可扩展的、可重复的和低成本的制备用于气体分离的无机膜的方法，与现有生产路线的高成本和可扩展性差形成鲜明对比，这阻碍了高性能无机膜在气体分离中的采用该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
