“…Besides, the SNW-1 COF nanoparticles embedded interracially polymerized thin-film composite was also reported as the forward osmosis desalination membranes. 145 The outer selective hollow fiber membrane with amine-rich SNW-1 performed well with a water flux rate of 31.5 L m -2 h -1 MPa -1 . Again, the incorporation of -COOH functional groups into the COF was demonstrated for the improved flux of water (64.2 L m -2 h -1 MPa -) due to the surface hydrophilicity of the membrane.…”

“…COFs are a class of robust two- or three-dimensional extended network materials known for their artistic structures and for their potential for a wide range of applications [ 113 , 114 ]. Wang et al [ 115 ] combined a new type of COF-SCU1 (firstly reported by Sichuan University [ 116 ]) with PAN powder to form a DMF solvent for electrospinning, thereby obtaining PAN/COF-SCU1 ENMs.…”

Water purification and water desalination via membrane technology are generally deemed as reliable supplementaries for abundant potable water. Electrospun nanofiber-based membranes (ENMs), benefitting from characteristics such as a higher specific surface area, higher porosity, lower thickness, and possession of attracted broad attention, has allowed it to evolve into a promising candidate rapidly. Here, great attention is placed on the current status of ENMs with two categories according to the roles of electrospun nanofiber layers: (i) nanofiber layer serving as a selective layer, (ii) nanofiber layer serving as supporting substrate. For the nanofiber layer’s role as a selective layer, this work presents the structures and properties of conventional ENMs and mixed matrix ENMs. Fabricating parameters and adjusting approaches such as polymer and cosolvent, inorganic and organic incorporation and surface modification are demonstrated in detail. It is crucial to have a matched selective layer for nanofiber layers acting as a supporting layer. The various selective layers fabricated on the nanofiber layer are put forward in this paper. The fabrication approaches include inorganic deposition, polymer coating, and interfacial polymerization. Lastly, future perspectives and the main challenges in the field concerning the use of ENMs for water treatment are discussed. It is expected that the progress of ENMs will promote the prosperity and utilization of various industries such as water treatment, environmental protection, healthcare, and energy storage.

“…Several studies introduced nanoparticles into the active layer of the membrane to enhance the stability and lower the tendency of fouling, including GO [ 313 , 314 ], silver (Ag) nanoparticles [ 315 ], zeolite [ 316 ], carbon nanotube [ 317 ], aquaporins [ 318 , 319 ], ZIFs [ 320 ], and covalent organic frameworks (COFs) [ 321 ]. Choi et al employed vacuum-assisted interfacial polymerization to incorporate Ag nanoparticles into outer selective-layer hollow fiber ( Figure 12 a) [ 315 ].…”

The aggravation of environmental problems such as water scarcity and air pollution has called upon the need for a sustainable solution globally. Membrane technology, owing to its simplicity, sustainability, and cost-effectiveness, has emerged as one of the favorable technologies for water and air purification. Among all of the membrane configurations, hollow fiber membranes hold promise due to their outstanding packing density and ease of module assembly. Herein, this review systematically outlines the fundamentals of hollow fiber membranes, which comprise the structural analyses and phase inversion mechanism. Furthermore, illustrations of the latest advances in the fabrication of organic, inorganic, and composite hollow fiber membranes are presented. Key findings on the utilization of hollow fiber membranes in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO), pervaporation, gas and vapor separation, membrane distillation, and membrane contactor are also reported. Moreover, the applications in nuclear waste treatment and biomedical fields such as hemodialysis and drug delivery are emphasized. Subsequently, the emerging R&D areas, precisely on green fabrication and modification techniques as well as sustainable materials for hollow fiber membranes, are highlighted. Last but not least, this review offers invigorating perspectives on the future directions for the design of next-generation hollow fiber membranes for various applications. As such, the comprehensive and critical insights gained in this review are anticipated to provide a new research doorway to stimulate the future development and optimization of hollow fiber membranes.
