项目摘要
1510442/1510411Lively/VasenkovApproximately 15% of domestic energy in the United States is consumed in separation processes. Composite membrane separators comprised of particles of advanced molecular sieve material embedded into a polymer film are a promising class of membranes with the potential to make meaningful impact on the energy efficiency of separation processes. The proposed research will establish experimental framework that allows resolving microscopic transport, sorption and structural properties of such composite membranes and finding relationships between these properties and the corresponding macroscopic properties relevant for applications in separations. The fundamental understanding of the microscopic properties of the composite membranes will lay the foundation for rationally designed composite membranes optimized for gas separations and pervaporation. Zeolitic imidazolate frameworks (ZIFs), a class of metal-organic frameworks (MOFs) that have zeolite-like structures, can be embedded into a glassy polymer matrix to form a mixed matrix membrane (MMM). Such membranes capture both the molecular sieving properties of the ZIF and the ease of processing associated with polymers. The main goal of this work is to develop a fundamental understanding of the relationship between the transport, sorption and structural properties of the MMM constituents and those of the corresponding neat materials. The PIs propose to use a synergetic strategy based on the application of several state-of-the-art and even unique NMR and sorption characterization techniques to achieve such resolution. The potentially transformative outcome of the proposed work is to enable the design of ZIF-polymer MMMs based on the understanding of changes of the transport, sorption and structural properties of the MMM constituents in comparison to those of the neat materials. The primary focus of the educational and outreach project plan is to establish a new inter-campus research mentoring program for K-12 and undergraduate students from underrepresented groups. This program will offer students participation in well-defined engineering projects, development of engaging animations and educational demonstrations related to membrane separations, presentation of these animations and demonstrations to younger students and participation in a student exchange between the UF and Georgia Tech groups.
1510442/1510411莱弗利/瓦森科夫大约15%的美国家庭能源消耗在分离过程中。由先进的分子筛材料颗粒嵌入到聚合物膜中的复合膜分离器是一类很有前途的膜,有可能对分离过程的能效产生重大影响。拟议的研究将建立实验框架,允许解决此类复合膜的微观传输、吸附和结构性质,并找到这些性质与相应的宏观性质之间的关系,这些性质与分离应用相关。对复合膜微观性质的基本了解将为合理设计用于气体分离和渗透汽化的复合膜奠定基础。分子筛咪唑骨架(ZIF)是一类具有类沸石结构的金属-有机骨架(MOF),它可以嵌入到玻璃聚合物基质中形成混合基质膜(MMM)。这种膜既具有ZIF的分子筛分特性,又具有与聚合物相关的加工简便性。这项工作的主要目标是对MMM组分的传输、吸附和结构性质与相应的整齐材料之间的关系有一个基本的了解。PI建议使用一种基于应用几种最先进甚至独特的核磁共振和吸附表征技术的协同策略来实现这样的分辨率。拟议工作的潜在变革性结果是使ZIF聚合物MMM的设计能够基于对MMM组分的传输、吸附和结构性质与纯材料相比的变化的理解。教育和推广项目计划的主要重点是为来自代表性不足群体的K-12和本科生建立一个新的校际研究指导计划。该项目将让学生参与定义明确的工程项目,开发与膜分离相关的引人入胜的动画和教育演示,向年轻学生展示这些动画和演示,并参与密歇根大学和佐治亚理工学院小组之间的学生交流。
