Abstract

Mixed matrix membranes (MMMs) composed of a glassy polymer (polysulfone) and the flexible metal organic framework NH₂-MIL-53(Al) exhibit excellent separation properties. In contrast to most reported membranes, CO₂/CH₄ separation selectivity increases with pressure, related to the flexibility of the filler.
