“…Some researchers have used ZIF-8 to prepare FO membranes for water treatment. Beh et al [24] used ZIF-8 to prepare a FO membrane with a high chemical stability and good water permeability, which was used to remove oil emulsion in water. Fu et al [25] developed a new type of forward osmosis membrane using a polyvinyl alcohol/polydopamine-coated zeolite imidazolate framework (PVA/PDA@ZIF-8), which improved the water flux and anti-fouling performance of the membrane.…”

Forward osmosis membranes have a wide range of applications in the field of water treatment. However, the application of seawater desalination is restricted, so the research of forward osmosis membranes for seawater desalination poses new challenges. In this study, zeolitic imidazolate framework-8 (ZIF-8) was synthesized by a mechanical stirring method, and its crystal structure, surface morphology, functional group characteristics, thermochemical stability, pore size distribution and specific surface area were analyzed. The cellulose acetate (CA)/ZIF-8 mixed matrix forward osmosis membrane was prepared by using the synthesized ZIF-8 as a modified additive. The effects of the additive ZIF-8 content, coagulation bath temperature, mixing temperature and heat treatment temperature on the properties of the CA/ZIF-8 forward osmosis membrane were systematically studied, and the causes were analyzed to determine the best membrane preparation parameters. The structure of the CA membrane and CA/ZIF-8 mixed matrix forward osmosis membranes prepared under the optimal conditions were characterized by Fourier Transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), contact angle and Atomic force microscope (AFM). Finally, the properties of the HTI membrane (Membrane manufactured by Hydration Technology Innovations Inc.), CA forward osmosis membrane and CA/ZIF-8 mixed matrix forward osmosis membrane were compared under laboratory conditions. For the CA membrane, the water flux and reverse salt flux reached 48.85 L·m−2·h−1 and 3.4 g·m−2·h−1, respectively. The reverse salt flux and water flux of the CA/ZIF-8 membrane are 2.84 g·m−2·h−1 and 50.14 L·m−2·h−1, respectively. ZIF-8 has a promising application in seawater desalination.

“…Modified MOFs have been frequently incorporated into TFNs in order to improve (1) MOF compatibility with the polymeric matrix in the selective polyamide layer, (2) MOF dispersibility in the organic/aqueous phase during interfacial polymerization, and/or (3) minimize MOF aggregation (e.g., ZIF-8, − HKUST-1, NH 2 -UiO-66 ,− ). In 2019, Zhao et al reported the synthesis of NH 2 -UiO-66 nanocrystals modified with polyvinylpyrrolidone (PVP), PVP-UiO-66-NH 2 to avoid the nanofiller aggregation and increase compatibility between the organic and inorganic counterparts .…”

“…Conventional FO membranes can suffer from low water flux, significant internal concentration polarization, and reverse solute flux (RSF), in which the draw solute leaks across the membrane into the feed solution. There are several examples in the literature of the incorporation of ZIF-8 and UiO-66 nanoparticles into interfacially polymerized FO membranes resulting in increased water permeance. ,,, Beh et al produced TFN FO membranes containing ZIF-8 nanoparticles or polystyrenesulfonate (PSS)-coated ZIF-8 nanoparticles via interfacial polymerization . The authors observed poor performance in the membranes containing uncoated ZIF-8 particles but reported an increase in water flux of 116% from a synthetic oil emulsion for the membranes containing PSS-coated particles.…”

Metal organic frameworks (MOFs) represent one of the largest classes of porous crystalline materials. MOFs have been increasingly applied as functionalizing agents for membranes because of their porosity, high surface area, small particle size, aspect ratio control, tuneability, compatibility with a polymeric network, and exuberance of diverse functional groups. In this comprehensive review paper, we discuss achievements, opportunities, and challenges related to the functionalization of different types of membranes using MOFs for water and wastewater treatment and desalination. The current synthesis and fabrication approaches of MOF-functionalized membranes were identified and critically reviewed. The effects of MOFs on membrane performance, including permeation, selectivity, and antifouling, were discussed. Also, the application of MOF-functionalized membranes in aqueous environments for conventional applications such as heavy metal removal and emerging applications such as resource recovery was enunciated. Finally, recommendations and future directions were provided for further improvement in the field of MOF-functionalized membranes for water treatment and reuse.

“…The connectivity and interactions of the cavities with target guest molecules can be controlled by altering the organic and inorganic building blocks [ 83 ]. The zeolitic imidazole framework (ZIF) is a sub-class of MOF which has been commonly used for nanocomposite membrane [ 84 , 85 , 86 , 87 , 88 ]. Although the MOF has been conventionally synthesized as a isotropic bulk crystal with a 3D network, nanosheet and nanofilm MOFs are gaining popularity owing to the merits stemming from the 3D porous framework and 2D intrinsic feature [ 89 ].…”

One of the critical aspects in the design of nanocomposite membrane is the selection of a well-matched pair of nanomaterials and a polymer matrix that suits their intended application. By making use of the fascinating flexibility of nanoscale materials, the functionalities of the resultant nanocomposite membranes can be tailored. The unique features demonstrated by nanomaterials are closely related to their dimensions, hence a greater attention is deserved for this critical aspect. Recognizing the impressive research efforts devoted to fine-tuning the nanocomposite membranes for a broad range of applications including gas and liquid separation, this review intends to discuss the selection criteria of nanostructured materials from the perspective of their dimensions for the production of high-performing nanocomposite membranes. Based on their dimension classifications, an overview of the characteristics of nanomaterials used for the development of nanocomposite membranes is presented. The advantages and roles of these nanomaterials in advancing the performance of the resultant nanocomposite membranes for gas and liquid separation are reviewed. By highlighting the importance of dimensions of nanomaterials that account for their intriguing structural and physical properties, the potential of these nanomaterials in the development of nanocomposite membranes can be fully harnessed.
