ABSTRACT
Mixed matrix membranes with zeolite fillers have attracted a lot of attention in membrane technology research due to their excellent advantages, such as high permeability and improved selectivity. Zeolite MMMs could be considered an ideal candidate for the purification industry since they combine the properties of polymeric matric and zeolite inorganic fillers. The application and fabrication techniques of zeolite-reinforced polymeric membranes have been comprehensively reviewed in this article to optimize interfacial interaction between the zeolite and the polymeric matrix. Compatibility between zeolite and polymer matrix can be improved with several methods, such as by applying high processing temperature during membrane formation, the silane modification, and priming on the particle’s surface, annealing that can relax the stress imposed on hollow fiber and result in higher packing density of polymer chains, and the introduction of an LMWA agent between the polymer matrix and inorganic particles. There have been numerous implementations to incorporate zeolite particles in polymer matrices in water purification applications and for gas separation due to their superior separation properties and size exclusion. Applications of zeolite MMMs were re-evaluated for a variety of industrial processes, including water purification, medical industry, catalytic, and gas separation.
