Metal Organic Framework Crystals in Mixed-Matrix Membranes: Impact of the Filler Morphology on the Gas Separation Performance.

Mixed-matrix membranes (MMMs) comprising NH-MIL-53(Al) and Matrimid or 6FDA-DAM have been investigated. The MOF loading has been varied between 5 and 20 wt%, while NH-MIL-53(Al) with three different morphologies: nanoparticles, nanorods and microneedles have been dispersed in Matrimid. The synthesized membranes have been tested in the separation of CO from CH in an equimolar mixture.
