Zeolite-enhanced polymer membrane performance for gas separation applications
Polymeric membranes are taking over the others in gas separation applications due to their satisfactory mechanical properties and favorable processing flexibility. But they are extremely restrained for gas separations by an upper trade-off limitation between the productivity and the selectivity. Recent advances suggest that dispersing highly selective rigid inserts such as zeolites and carbon molecular sieves into polymers can produce novel membrane materials with improved gas mixture pennselectivity,possibly providing as a promising altemative to the conventional membranes.In our work, we have attempted to embed beta zeolite into polyimide (PI) for fabricating fiat-sheet films for gas permeations.These membranes have been prepared on the smooth glass wafer by the solution-casting method from the polymer dope, resulting in the dispersed zeolite particles well-distributed in the continuous polymer matrix as reflected by the SEM image.
