X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis were done to characterize the membranes.

A Metal Chelating Porous Polymeric Support: The Missing Link for a Defect‐Free Metal–Organic Framework Composite Membrane

“…ZIF‐8 layers have been successfully grown on Nylon, polyacrylonitrile (PAN), polyethylenimine (PEI), polyethersulfone (PES), polyvinylidene difluoride (PVDF), and other polymeric materials . To obtain a continuous, dense, thin, selective ZIF‐8 layer, both the properties of the support and the synthesis method are important.…”

“…To obtain a continuous, dense, thin, selective ZIF‐8 layer, both the properties of the support and the synthesis method are important. The main synthesis methods used for obtaining ZIF‐8 layers on polymer supports can be classified as follows: 1) in situ, 2) secondary seeded growth, 3) contra‐diffusion, 4) interfacial synthesis, and 5) layer‐by‐layer . It has been shown that modification of the polymer support prior to ZIF‐8 growth may enhance final membrane performance .…”

ZIF‐8 membrane synthesized via covalent‐assisted seeding on polyimide substrate for pervaporation dehydration

“…Conventionally, a large diversity of inorganic materials, such as porous alumina (Al 2 O 3 ), porous zinc oxide (ZnO), and stainless‐steel nets, have been reported as substrates for ZIF membranes because of their good mechanical strength as well as the high resistance to the high temperatures and strong solvents. Alternatively, polymeric substrates with the better processibility and lower cost may have superior industrial potential, but they generally suffer from the poor stability in harsh circumstance . To date, several synthesis protocols have been reported to fabricate ZIF membranes on polymeric substrates, which can be broadly divided into two categories: in situ growth and secondary growth .…”
