The incorporation of several types of zeolite in PDMS membranes is stu
died, by measuring the tensile strength, xylene sorption, and density
of the membranes. The zeolite is shown to be involved in the cross-lin
king of the membrane. The interaction between the PDMS matrix and the
zeolites results in reinforced membranes in the case of zeolite Y. The
parameters influencing the dispersion of the zeolite in the membrane
are investigated, as well as several aspects of the preparation method
. Finally, the idea of cross-linking is applied to explain the results
of water/ethanol pervaporation.
