Locating the binding domains in a highly selective mixed matrix membrane via synchrotron IR microspectroscopy

Abstract: The binding domains within a mixed matrix membrane (MMM) that is selective for CO comprising MFM-300(Al) and the polymer 6FDA-Durene-DABA have been established via in situ synchrotron IR microspectroscopy. The MOF crystals are fully accessible and play a critical role in the binding of CO, creating a selective pathway to promote permeation of CO within and through the MMM. This study reveals directly the molecular mechanism for the overall enhanced performance of this MMM in terms of permeability, solubility a… Show more

“…The porous filler material of MMMs is usually thought to contribute to the gas separation properties of the MMMs and could even enhance the selectivity of the MMMs compared to the neat polymer membrane. , Here the separation of CO 2 and CH 4 is used to test for this effect (Figure S5). The gas uptake in the porous Al-fum for CO 2 and CH 4 at 870 mmHg was 3.8 mmol/g and 1.4 mmol/g, respectively.…”

“…Jacques et al 159 used a surface modifier (dimethoxy-methylsilylpropyl-modified-poly, ethylene imine) to coat MFM-300(Al) particles with polymer 6FDA-durene-DABA to make MMMs. In situ synchronous infrared microscopy was used for the first time for mechanism analysis.…”
