提案题目：NIRT：用于气体分离的中空纤维聚合物/多孔层纳米复合膜的制备提案编号：cts -0403574首席研究员：Michael tsapatsi机构：明尼苏达大学双城分校该提案是根据纳米科学与工程计划（NSF 03-043， NIRT类别）收到的。本项目的目的是研究用于气体分离技术的纳米结构无机/聚合物复合材料的合成和性能。粘土薄片将被掺入聚合物中，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一个潜在的基础。探讨不同长度尺度下结构性质对渗透率的影响。通过跨越几个长度尺度，包括纳米尺度，该团队将有助于了解纳米尺度材料的基本行为。该团队计划将他们的工作扩展到开发制造分层复合材料的新方法。就更广泛的影响而言，教育和推广活动以K-12教师的本科生研究和研究经验为中心。与一个捷克小组的合作将集中于开发带电的聚电解质，这种电解质可用于制造多孔层纳米复合膜。与工业合作伙伴的紧密联系可以帮助转移制造改进膜的技术。

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.
