Layered Silicates with 3-D Microporous Layers: Synthesis and Modification for Membrane Applications TSE03-B (&E)

摘要提案标题：TSE：具有三维微孔层的层状硅酸盐：膜应用的合成和改性提案编号：CTS-0327811首席研究员：Michael Tsapatsis机构：明尼苏达大学本提案的目的是合成具有三维孔隙率的新型层状硅酸盐材料（AMH-3）作为一类新的膜。 这项工作将侧重于了解AMH-3的生长，以指导其他三维微孔层的合成，并修改AMH-3，使其与纳米复合材料加工技术兼容，并定制硅酸盐层的气体吸附性能。 表征技术将包括布鲁克海文国家实验室和NIST的SEM、TEM、NMR、IR、拉曼、气体吸附以及同步加速器X射线和中子粉末衍射。 当将这些无机材料掺入聚合物材料中时，由于微孔组分的上级分子识别能力，它们应保持聚合物可加工性，同时改善选择性渗透性能。 就更广泛的影响而言，这项工作应该对膜技术产生影响，对催化剂、传感器和吸附剂等纳米结构功能材料的产生产生更广泛的影响。 这项工作将有助于研究生和本科生在一个新兴的领域的基本利益和技术和环境意义的教育。

AbstractProposal Title: TSE: Layered Silicates with 3-D Microporous Layers: Synthesis and Modification for Membrane ApplicationsProposal Number: CTS-0327811Principal Investigator: Michael TsapatsisInstitution: University of MinnesotaThe objective of this proposal is to synthesize novel layered silicate materials with three-dimensional porosity (AMH-3) as a new class of membranes. The work will focus on understanding the growth of AMH-3 to guide the synthesis of other three-dimensional microporous layers and to modify AMH-3 to make it compatible with nanocomposite processing techniques and to tailor the gas adsorption properties of the silicate layers. Characterization techniques will include SEM, TEM, NMR, IR, Raman, gas adsorption as well as synchrotron X-ray and neutron powder diffraction at Brookhaven National Laboratory and NIST. When these inorganic materials are incorporated in polymeric materials, they should retain polymer processability while improving permselective properties due to the superior ability for molecular recognition of the microporous component. In terms of the broader impacts, this work should have an impact on membrane technology with wider implications in the generation of nanostructured functional materials such as catalysts, sensors and adsorbents. The work will contribute to the education of graduate and undergraduate students in an emerging area of fundamental interest and of technological and environmental significance.
