Resumo(s)

Mixed matrix membranes (MMM) are heavily studied and the main concern by researchers is the difficulty to obtain a high selectivity membrane with low defects, mainly interfacial voids due to the poor interaction between polymer matrix and filler. The functionalization of zeolite surface in Poly-EtherSulphone (PES)/Silico-AluminoPhosphate-34 (SAPO- 34) led to membranes with higher compatibility. Recently, the use of ionic liquids in the particles surface to improve the gas permeability and separation efficiency has presented advanced results. The aim of this work is to compare the separation efficiency of CO2 and N2 in permeance and selectivity criteria. The use of the ionic liquid (IL) [emim][Tf2N] showed an increase in selectivity and in CO2 permeance due to promoting a better separation of the dispersant in the polymeric matrix when compared to a film with the same composition without the IL treatment.
