The proposed approach to be explored through this I/UCRC Fundamental Research Program project utilizes interfacial polymerization (IP) to create a barrier layer on pre-patterned ultrafiltration (UF) membrane supports to create functional patterned thin film composite (TFC) membranes. The specific objectives are (1) generation of new knowledge regarding (i) the IP process dynamics on patterned UF membranes, (ii) the structure of the resulting barrier layer, and (iii) their dependence on major processing parameters; and (2) examination of the influence of specific surface pattern characteristics on salt deposition (fouling) during desalination.This work will enable a non-chemical approach to the fabrication of TFC membranes with reduced fouling and improved energy efficiency; the study will also advance current knowledge as to how surface topography affects membrane fouling during active filtration, which in turn will guide the design of optimized surface patterns for specific separation applications. The work is supported by the Industry Advisory Board as well as individual industry members of the center and has the potential to extend the center?s portfolio while potentially attracting new members. The proposed work will leverage the exceptional infrastructure for innovation in education and outreach at CU-Boulder to provide new and inspirational educational experiences, with a focus on membrane technology, for students at all levels.

通过这个I/UCRC基础研究计划项目探索的拟议方法利用界面聚合（IP）在预图案化超滤（UF）膜支撑物上形成阻挡层，以形成功能性图案化薄膜复合（TFC）膜。具体目标是（1）产生关于（i）图案化UF膜上的IP工艺动力学、（ii）所得阻挡层的结构和（iii）它们对主要工艺参数的依赖性的新知识;以及（2）检验在脱盐过程中比表面图案特征对盐沉积（污垢）的影响。这项工作将使非-本研究旨在通过化学方法来制造具有减少污染和提高能源效率的TFC膜;该研究还将推进当前关于表面形貌如何影响主动过滤过程中膜污染的知识，这反过来又将指导特定分离应用的优化表面图案的设计。 这项工作得到了行业咨询委员会以及该中心个别行业成员的支持，并有可能扩大该中心？的投资组合，同时有可能吸引新成员。拟议的工作将利用CU-Boulder的教育和推广创新的特殊基础设施，为各级学生提供新的和鼓舞人心的教育体验，重点是膜技术。
