Novel mixed matrix membranes (MMMs) based on polyethersulfone (PES) and [Al12O(OH)18 (H2O)3(btc)6] (btc: benzene-1,3,5-tricarboxylic acid), also known as Material of Institute Lavoisier (MIL)-96 (Al), fillers were successfully prepared using a conventional printing method with the wet phase inversion technique. Membranes for gas separation were successfully prepared using PES 35% w/w in N,N′-dimethylacetamide (DMAc).Variations in percent addition of fillers included 5%, 10%, 20%, and 30% w/w to observe gas separation performance. The produced PES/MIL-96 (Al) MMMs did not show any chemical interactions based on fourier transform infrared analysis. The fabricated membrane has a finger-like structure, as demonstrated by scanning electron microscopy images. Gas separation performance in MMMs was observed in N2, O2, and CO2 gases. Membrane permeability showed an increase as the number of fillers was increased. The optimum selectivity of the membranes for the separation of CO2/N2 and CO2/O2 gases was achieved with the addition of 20% fillers with increases of 155% and 86%, respectively, compared to pure PES membranes. Agglomeration was observed with the addition of 30% particle filler to the membranes, which resulted in decreased membrane selectivity.
