Mixed matrix membranes with HF acid etched ZSM-5 for ethanol/water separation: Preparation and pervaporation performance

► MMMs were prepared by incorporation of surface etched ZSM-5 with HF acid into PDMS membranes. ► Effect of the zeolite surface morphology on interfacial integration and pervaporation performance of ZSM-5/PDMS MMMs. ► The pervaporation mechanism of MMMs was investigated based on sorption experiment. ► MMMs filled with etched ZSM-5 showed much better separation performance than that filled with non-etched ones.
