Metal-organic framework (MOF)-containing polymeric membranes have enormous promise for gas separation. To lessen the membrane's flawed structure, it is essential to precisely control the adhesion between MOFs and polymer matrices. The interaction between MOFs and the polymer matrix, which has a tendency to aggregate on the membranes, is restricted by their partially inorganic structure. This article describes an interfacial technique that improves the interfacial interaction between filler and Polyamide (PA) matrices by post-synthetically functionalizing MIL-53 (Al) with ionic liquids (ILs) to create an IL@MIL-53 (Al) composite. IL@MIL-53 (Al) and PA matrices have close contact, which makes uniform dispersion visible in morphological analyses. MMMs were characterized using Fourier transform infrared (FTIR) spectra and scanning electron microscopy (SEM). The behavior of gas separation was investigated by measuring one. The gas permeability of four different gases CH4, N2, O2, and CO2 was evaluated for both pure and composite membranes using a constant-volume variable pressure method. The CO2 permeance was 44 barrer at 2 % weight percent of MIL-53 (Al) nanofiller, which was noticeably greater than that of the pure Polyamide (PA) membrane. Because of ILs' strong affinity and CO2 solubility, introducing them into the MOFs pores will adjust pore size while improving adsorption selectivity. Functionalization of ILs on the cores of the MIL-53 (Al) structure is a successful tactic that allows for a wide variety of fillers to be chosen in terms of commercialization.
