In this study, the mixed matrix membranes of PEBA/NaX zeolite were by solvent evaporation method for gas separation application. The effects of nano NaX zeolite loading on the N2 and CO2 permeation were investigated. The zeolite nanoparticles were synthesis by hydrothermal method using microwave heating and characterized by the XRD analysis. The SEM analysis showed that the zeolite nanoparticle well dispersed in the PEBA matrix. The experimental results revealed that incorporation of nano NaX zeolite to PEBA membranes decreased the N2 and CO2 permeabilities due to the barrier effect of the zeolite particle, while the CO2/N2 ideal selectivity significantly enhanced. It can be concluded that the addition of zeolite nanoparticle into the PEBA matrix had considerable effect on the membrane structure and separation properties
