Universidad de Zaragoza (orcid)0000-0002-5967-2827 NH2-MIL-53(Al) and NH2-MIL-101(Al) in sulfur-containing copolyimide mixed matrix membranes for gas separation 2013 Amino functionalized MOFs (NH2-MIL-53(Al) or NH2-MIL-101(Al)) were used as dispersed phase in the fabrication of mixed matrix membranes (MMMs) with a polymer matrix of sulfur-containing copolyimides (6FDA:DSDA/4MPD:4,4’-SDA 1:1 (polymer P1) or 6FDA/4MPD:4,4’-SDA 1:1 (polymer P2)). The gas separation properties of the MMMs obtained were tested for permeation of H2, CH4 and CO2. Membranes comprising polymer P1 showed better interaction with the fillers used than polymer P2, and therefore better separation properties, especially for NH2-MIL-101(Al). Upon NH2-MIL-101(Al) loading the performance of pure polymer was improved approaching the Robeson 1991 H2/CH4 and CO2/CH4 upper bound limits with high permeabilities, e.g. 114, 71 and 1.7 Barrer for H2, CO2 and CH4, respectively, using 10 wt.% NH2-MIL-101(Al)@P1. These improvements are related to the pore size of the filler, the flexibility and functional groups of sulfone-containing DSDA, and polymer rigidification.
