Description	Novel mixed matrix membranes were obtained by the dispersion of montmorillonite (MMT) nanoparticles in poly(phenylene-iso-phtalamide) (PA) matrix. Membrane structure was determined on the basis of density measurement and morphology study by SEM. The effect of MMT inclusion on membrane hydrophilic properties was estimated by the measurement of contact angles of water, methanol, and toluene, respectively, and the calculation of surface tension. Transport properties of PA/MMT membranes were studied by use of swelling and pervaporation tests. The prepared membranes were used in the pervaporation of methanol–toluene mixtures. Total fluxes and separation factors, such as permeabilities and selectivities, were determined. It was established that the improvement of some physicochemical properties and transport parameters occurs only by inclusion up to 3 wt% MMT in the PA matrix.
