Abstract
To gain insight into the influence of metal–organic framework (MOF) fillers and polymers
on membrane performance, eight different composites were studied by combining four
MOFs and two polymers. MOF materials (NH2‐MIL‐53(Al), MIL‐69(Al), MIL‐96(Al) and ZIF‐94) with various chemical functionalities,
topologies, and dimensionalities of porosity were employed as fillers, and two typical
polymers with different permeability‐selectivity properties (6FDA‐DAM and Pebax) were
selected as matrices. The best‐performing MOF–polymer composites were prepared by
loading 25 wt % of MIL‐96(Al) as filler, which improved the permeability and selectivity
of 6FDA‐DAM to 32 and 10 %, while for Pebax they were enhanced to 25 and 18 %, respectively.
The observed differences in membrane performance in the separation of CO2 from N2 are explained on the basis of gas solubility, diffusivity properties, and compatibility
between the filler and polymer phases.
