title: Molecularly Tuned Free Volume of Vapor Cross-Linked 6FDA-Durene/ZIF-71 MMMs for H2/CO2Separation at 150 °C.
abstract: The H2/CO2separation properties of di/triamine vapor cross-linked mixed matrix membranes with molecularly tuned free-volume at 150 °C are reported. Free-volume is molecularly tuned by altering the degree of chain-motion using cross-linkers with different chain lengths. A more restricted degree of chain-motion is achieved in the cross-linked network and the resultant membrane has a higher H2/CO2selectivity at 150 °C.
