Highly promoted CO₂ separation of poly(ether-block-amide) based mixed matrix membranes using MOFs@aminoclay architectures as fillers.

ABSTRACT: In this research, a collection of new composites constructed from aminoclays (MgAC and ZrAC) and MOFs are inserted into the PEBAX matrix for gas separation inspections. In fabricated UiO-66-(COOH)₂@CuBDC@MgAC and MIL-121@CuBDC@MgAC composites series, amine groups of MgAC, unoccupied Cu ions of CuBDC and free carboxylic acid in the pores of UiO-66-(COOH)₂ and MIL-121 are intensely involved in superior CO₂ permeability of prepared MMMs from these composites. Besides, the nanosheet formation of CuBDC MOF induced by MgAC sheets develops the interphase regions (MOF-MOF and PEBAX-composites) which are also responsible for such obtained CO₂ permeability against N₂. Additionally, lower pore diameter of CuBDC in comparison with UiO-66-(COOH)
