“…Rajendaren et al prepared ZIF‐8/polyethersulfone (PES)‐polyethylene glycol composite membrane, ZIF‐8 was used as a hydrophobic filler, and the introduction of ZIF‐8 increased the WCA of PES membrane from the original 83.4° to 103.9° 53 . Zhang et al prepared ZIF‐67/polyacrylonitrile (PAN) nanofiber membrane, ZIF‐67 was used as a hydrophobic filler, and the introduction of ZIF‐67 made the maximum contact angle of nanofiber membrane reach 117° 54 .…”

The high internal phase emulsion (HIPE) template method is widely used to prepare porous functional materials because of its designable emulsion components and adjustable porosity. Herein, amphiphilic gelatin (GE) as the sole emulsion stabilizer, and no additional emulsifiers were added to prepare a stable GE‐HIPE membrane and its zeolitic imidazolate framework‐67 (ZIF‐67) hybrid composite membrane. The ZIF‐67/GE‐HIPE composite membrane has good lipophilicity by constructing dual micro‐nano structures by HIPE template and in situ growth of ZIF‐67. When ZIF‐67 was grown in situ, the water contact angle (CA) increased from 58.1 ± 2° for the GE membrane to 121 ± 1.9° for ZIF‐67/GE‐HIPE composite membranes. Besides, the minimum CA of organic solvent is 4.5 ± 0.7° (n‐hexane). The ZIF‐67/GE‐HIPE composite membranes exhibit good O/W emulsion separation properties and adsorption removal ability of organic pollutants. After 10 times of recycling emulsion separation, the emulsion separation capacity of the membrane was still greater than 99.4%. The lipophilic dye removal rate of the ZIF‐67/GE‐HIPE composite membrane was 2.37 times higher than that of GE‐HIPE, and the adsorption process conforms to the pseudo‐second‐order model. Thus, this work provides a strategy for the preparation of GE‐based hydrophobic modified membrane and also presents a typical treatment of adsorption‐separation of lipophilic substances.

“…Apart from having compatibility with several solvents and gas mixtures, some beneficial characteristics of PES supports, namely, pore size, porosity and thickness, are other key factors of this membrane which enhance the separation efficiency through solvent retention, compatibility and quantity in the membrane system. Therefore, as shown in Table S1, many other research studies used PES as the support. ,− The structure of PES support can be seen in a SEM image (Figure a).…”

The idea of establishing faster/facilitated transport through liquid membranes (LMs) is both theoretically fascinating and promising for applications. One of the most selective, along with lots of desirable promising forms of LMs, is supported liquid membranes (SLMs). Since the introduction of the idea of SLMs a few decades ago, research activities in this sector have been continuously increased. Through a comprehensive analysis of the current state of the art, this review demonstrates the design and application considerations that must be made when determining whether to employ polymeric or ceramic supports in SLMs for gas separation. Following a thorough analysis of the principles of LMs, including their chronology, transport mechanism, and advantages and disadvantages are presented. The various configurations suggested up to date, their road from the laboratory to practical implementation, and their performance are discussed. Finally, potential challenges and opportunities are outlined.
