dc.description.abstractThe use of zeolites as fillers in mixed matrix membranes (MMM) in gas separation is a well-studied subject. The difficulties to produce a membrane with high selectivity and low defects in the zeolite/polymer interface are well documented. Many researchers have reported that the functionalization of zeolite surface led to membranes with higher compatibility with zeolite/polymer via using silane groups, amine groups, or ionic liquids in the particles surface to improve the gas permeability and separation efficiency. This article aims to describe, summarize and discuss the use of amines, silanes and ionic liquids as surface modifiers. Those modifications lead to an increase in selectivity and in polymer/filler compatibility by increasing the dispersion of the particles in the polymeric matrix, which represents the most recent subjects in the development of MMMs. The performance results surpass by many times the efficiency of regular MMM synthesis. The work is focused specifically on MMMs using the silico-aluminophosphate SAPO-34 due its potential, diverging from general reviews, and focusing on a specific case discussing recent works and new ways to develop this theme through a deeper study. All possible SAPO-34 surface modifications are compared, and new possible membrane modifications and treatments are proposed.pt_PT
