Along with the key factor for improving separation processability, development of membranes with high selectivity without sacrificing permeability is crucial for industrial application of pervaporation. Even though polymeric membranes have been widely used, they still have some limitations such as the trade-off between permeability and selectivity as well as low durability against harsh conditions that hinder their commercialization. The incorporation of nanostructures within polymeric matrices has been considered to be highly promising for effectively controlling molecular separation. Surface-modified zeolites are a potential material for fabricating nanocomposite membrane. The presence of inorganic nanostructures on zeolite surface, in addition to zeolite well-defined nanocrystalline structures, allows the creation of nanocomposite membrane with high separation factor. Furthermore, the high chemical, thermal, and mechanical stabilities of zeolite are expected to improve the durability of nanocomposite membranes. However, fabricating defect-free zeolite-based nanocomposite membranes is challenging due to zeolite–polymer compatibility and dispersibility. This chapter summarizes the latest development of zeolite-based polymer nanocomposite membranes for pervaporation, including preparation methods, separation performances, water/alcohol separation mechanisms, and challenges of zeolite-filled polymeric membrane fabrication.
