Proposal Title: NTE: Engineering of Nanospaces: Hybrid Membranes for Environmentally Important SeparationsProposal Number: CTS-0329386Principal Investigator: David FordInstitution: Texas A&M UniversityThe objective of this proposal is to design, synthesize, and evaluate organic-inorganic hybrid membranes for applications such as removal of trace volatile organic contaminants from air or water streams. The membrane processes employed for these two applications will be vapor permeation and pervaporation. Membrane materials will be based on mesoporous inorganic frameworks with average pore sizes ranging from 1 to 100 nm. The porous spaces of the framework will be modified by chemically attaching dendrimeric molecules to the pore surfaces. This architecture will afford a degree of simultaneous control over both the chemistry and free volume of the membrane, which is difficult to achieve with polymeric or inorganic materials. Design goals will be accomplished by manipulating the dendrimer chemistry, pore geometry, and dendrimer surface density. Organic dendrimers will be designed to adsorb target contaminants without permanently sequestering them. In terms of the broader impacts, the students will benefit from an interdisciplinary experience that connects materials synthesis and separation processes. The membranes produced have the potential to remove toxic contaminants before they enter the environment.

提案标题：NTE：纳米空间工程：用于环境重要分离的混合膜提案编号：CTS-0329386 首席研究员：David Ford 机构：德克萨斯 A&M 大学 该提案的目的是设计、合成和评估用于去除等应用的有机-无机混合膜空气或水流中的微量挥发性有机污染物。 这两种应用所采用的膜工艺是蒸气渗透和全蒸发。 膜材料将基于平均孔径为1至100纳米的介孔无机框架。 通过将树枝状分子化学附着到孔表面，可以改变框架的多孔空间。 这种结构将提供对膜的化学性质和自由体积的一定程度的同时控制，这是用聚合物或无机材料难以实现的。 设计目标将通过操纵树枝状聚合物化学、孔几何形状和树枝状聚合物表面密度来实现。 有机树枝状聚合物将被设计用于吸附目标污染物，而不是永久隔离它们。就更广泛的影响而言，学生将受益于连接材料合成和分离过程的跨学科经验。 所生产的膜有可能在有毒污染物进入环境之前将其去除。
