The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to develop materials to purify water for drinking. This project advances materials that can be used for advanced filtration. The research is focused on the removal of many classes of compounds from drinking water, such as heavy metals and polyfluoroalkyl substances. These pervasive substances have been linked to adverse human health effects and they are persistent in the environment. This project will develop a point-of-use solution that will have significant impact on providing access to drinking water. These materials are safe for drinking water since they are based on natural materials and polymers already used in water purification technology.The propsoed project will focus on (1) Optimization of ion exchange (IX) materials, and (2) Scaling-up the production of these materials to pilot scale or higher. Optimization of adsorption capacity, and water flux will be done while minimizing the cost of manufacturing. The technology is a very thin layer of IX resin attached to a nanoscale support. The support material provides structural rigidity and eliminates the need for cross-linking, which leads to degradation of the traditional IX materials. The proposed technology increases surface area, binding site accessibility, and improves adsorption kinetics to make these materials cheaper and more efficient than the competing products. The polymers are permanently bound to the support materials using "click chemistry" to ensure their retention in the filter modules over time and with repeated use.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/商业潜力是开发净化饮用水的材料。 该项目开发了可用于高级过滤的材料。 该研究的重点是去除饮用水中的多种化合物，例如重金属和多氟烷基物质。 这些普遍存在的物质对人类健康产生不利影响，并且它们在环境中持续存在。 该项目将开发一种使用点解决方案，将对提供饮用水产生重大影响。这些材料对饮用水来说是安全的，因为它们基于已用于水净化技术的天然材料和聚合物。拟议项目将重点关注 (1) 离子交换 (IX) 材料的优化，以及 (2) 扩大生产规模这些材料达到中试规模或更高规模。 将优化吸附能力和水通量，同时最大限度地降低制造成本。 该技术是在纳米级支撑物上附着一层非常薄的 IX 树脂。 支撑材料提供了结构刚性并消除了交联的需要，交联会导致传统 IX 材料的降解。 所提出的技术增加了表面积、结合位点可及性，并改善了吸附动力学，使这些材料比竞争产品更便宜、更高效。 使用“点击化学”将聚合物永久地结合到支撑材料上，以确保它们随着时间的推移和重复使用而保留在过滤器模块中。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和技术进行评估，被认为值得支持。更广泛的影响审查标准。
