Title: Tunable composite membranes for gas separations. Progress report, August 1, 1995--October 31, 1995

Abstract

The fourth quarter of continued to see progress on five fronts: (a) instrument development, (2) polymer synthesis, (3) membrane fabrication and microscopy, (4) composite membrane fabrication and (5) permeability measurements. We have examined zeolite-polymer composite membranes with different zeolite loadings (10%, 25% and 50% by weight) using light and scanning electron microscopies in order to determine particle size distribution and homogeneity of dispersion. The distribution of zeolite (NaX) particles was fairly uniform across the length and width and excellent across the thickness of the film. The NaX crystallites displayed a reasonably uniform size distribution ranging between 2--5 {mu}m and this was carried over into the composite films made with the lower loading levels indicating that aggregation during the casting process was not occurring. At the highest loadings some clustering of the zeolites was observed.
