Proposal Title: NIRT: Fabrication of Hollow-fiber Polymer/Porous-layer Nanocomposite Membranes for Gas SeparationsProposal Number: CTS-0403574Principal Investigator: Michael TsapatsisInstitution: University of Minnesota - Twin CitiesThis proposal was received in response to Nanoscale Science and Engineering initiative, NSF 03-043, category NIRT. The objective of this project is to study the synthesis and properties of nanostructured inorganic/polymer composites for application in gas separation technology. Flakes of clay will be incorporated into polymers and fabricated into tubes used in gas separation experiments. The blend of experiment and modeling will provide an underlying basis for understanding the compatibility of the polymeric and inorganic constituents. The effect of structural properties on permeability at different length scales will be probed. By spanning several length scales, including the nanoscale, the team will contribute to fundamental knowledge regarding the behavior of nanoscale materials. The team plans to extend their work to developing new approaches to making layered composites. In terms of the broader impacts, education and outreach activities center on undergraduate research and research experiences for K-12 teachers. A collaborative effort with a Czech group will focus on the development of charged, polyelectrolytes, which could be used in the fabrication of porous layer nanocomposite membranes. There are strong ties to industrial partners that can help transfer technology in the fabrication of improved membranes.

提案标题：NIRT：中空纤维聚合物/多孔层纳米复合气体分离膜的制备方案编号：CTS-0403574主要研究者：Michael Tsapatsis机构： 明尼苏达大学-双城这个建议是在响应纳米科学和工程倡议，NSF 03 - 043，类别NIRT。 本计画的目的是研究奈米结构无机/聚合物复合材料的合成与性质，以应用于气体分离技术。 粘土薄片将被掺入聚合物中，并制成用于气体分离实验的管子。 实验和建模的结合将为理解聚合物和无机组分的相容性提供基础。 将探讨不同长度尺度下结构特性对渗透率的影响。 通过跨越几个长度尺度，包括纳米尺度，该团队将有助于有关纳米材料行为的基础知识。 该团队计划将他们的工作扩展到开发制造层状复合材料的新方法。 就更广泛的影响而言，教育和推广活动集中在本科生研究和K-12教师的研究经验上。 与一个捷克小组的合作将集中在带电聚电解质的开发上，这种聚电解质可用于制造多孔层纳米复合膜。与工业合作伙伴有着密切的联系，可以帮助转让制造改进膜的技术。
