Abstract

Abstract : An unusual but highly desired increase in the separation selectivity of C3 H6 /C3 H8 under high pressures was found on the PDMS-coated ZIF-8 polycrystalline membrane. Abstract : The polydimethylsiloxane (PDMS) coating penetrated into the underneath ZIF-8 polycrystalline membrane not only blocking the inter-crystalline defects but also hindering the flexibility of the ZIF-8 framework, resulting in an unusual and highly desired increase in the separation selectivity of the C3 H6 /C3 H8 mixture under high feeding pressures.
