摘要：

The incorporation of zeolites in PI (polyimide) is investigated, aiming at higher fluxes and selectivities in membrane applications. Remarkable differences are found in comparison with the earlier reported incorporation of zeolites in PDMS (poly(dimethylsiloxane)): the adhesion between the PI and the zeolite is bad, resulting in weak membranes. The sorption of xylenes in the membrane is used to study the impact of sorption and diffusion in potential membrane applications. The preparation method used induces anisotropy in the membrane.
