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 CH/CH mixture under high feeding pressures.
聚二甲基硅氧烷（PDMS）涂层渗透到下方的ZIF-8多晶膜中，不仅堵塞了晶间缺陷，还阻碍了ZIF-8骨架的柔韧性，从而在高进料压力下使CH/CH混合物的分离选择性出现了异常且非常理想的提高。
