(462c) Mixed-Linker Zeolitic Imidazolate Framework (ZIF) Materials and Scalable Membrane Processing on Polymeric Hollow Fibers

This talk will describe our recent progress in the synthesis and properties of ZIF-type MOF materials for molecular separation applications, and their subsequent use in the scalable fabrication of molecular sieving membranes on polymeric hollow fibers. New separations technology is key to increased energy efficiency in the chemical sector, as well as the efficient production of clean and renewable fuels. It is hypothesized that ZIF materials may find successful applications in this area. Towards this goal, we will first discuss approaches to controlling the pore structure and separation properties of ZIF materials via mixed-linker synthesis. We then discuss the processing and use of these MOF materials in the fabrication of membranes for gas and hydrocarbon separations. The transport properties of such membranes are discussed. We will discuss some key scientific and engineering questions whose resolution (via combined experimental and computational methods) may enable the successful application of ZIF membranes in separations processes.
