PDMS/Zeolite mixed matrix membranes for separation of hydrocarbon isomers

In this study, a new type of membranes composed of interpenetrating polymeric and inorganic particle matrices has been introduced as mixed matrix membranes. a new method was applied for the fabrication of PDMS/5A- Zeolite membranes and their performance in separation of hydrocarbon isomers was investigated at different zeolite loadings. No improvement with respect to the ideal and real selectivity of the original polymeric membrane could be obtained for the investigated mixed matrix membranes. This trend can be due to the weak interactions occurring in the zeolite–polymer interface which play a significant role in the results obtained.
