MOF-based Mixed-Matrix Membranes for Hazardous Chemical Capture
Abstract
The objective of this effort is to investigate the design and synthesis of metal-organic framework-based mixed-matrix membranes. Composite materials combining metal-organic frameworks (MOFs) with polymer materials will be investigated. A variety of MOFs will be studied, but will initially focus on UiO-66 and HKUST- 1 . The effect of MOF composition, particle morphology, and particle size will be studied. In addition, blended mixed-matrix membranes containjng more than one MOF will be explored. Binrung agents including polyvinylidcne fluoride, polytetrafluorocthylene, and styrene butadiene will be investigated. Membrane processing factors will be studied for optimal film density and performance including polymer:MOF ratio, coating thickness, drying temperature, and drying times. Composite materials will be fully characterized for crystallinity, thermal stability. and microporosity. Mixed-matrix membranes will be tested for gas sequestration and chemical detoxification capabilities. Potential analytes of interest include chemical warfare agent simulants and toxic industrial chemicals (ammonia, nitrogen dioxide, and sulfur dioxide).
