Homogeneous polymer–zeolite nanocomposite membranes by incorporating dispersible template-removed zeolitenanocrystals

Abstract

Homogeneous polymerzeolite membranes were fabricated by incorporation of dispersible template-removed zeolite A nanocrystals into polysulfone. SEM, XRD, N2 adsorption–desorption measurements were used to characterize the zeolite A nanocrystals. The uniformity of the polysulfone–zeolite A nanocomposite membranes was examined by SEM. Air separation measurements of the nanocomposite membranes showed enhanced performance in O2/N2 selectivity and O2 permeability. The polysulfone–zeolite nanocomposite membrane with 25 wt% zeolite A loading exhibited an O2/N2 selectivity of 7.7 and O2 permeability of 1.8 Barrers whereas the pure polysulfone membrane had an O2/N2 selectivity of 5.9 and O2 permeability of 1.3 Barrers.
