“…In the preparation of TFC membranes, a porous substrate serves as a scaffold for the formation of a polyamide (PA) selective layer on the surface through the interfacial polymerization (IP) between acyl chloride monomers and multifunctional amine monomers. This signifies that the physicochemical properties of the porous substrate surface have great influences on the formation of the constructed PA selective layer. − On the other hand, the porous membrane substrates, whose materials of construction could be different from that of the top selective layer, are fabricated in the same manner as that for the preparation of the low-pressure-driven membranes (MF and UF membranes) which typically uses the nonsolvent-induced phase separation (NIPS) process …”

Metal–phenolic networks (MPNs) are novel supramolecular materials with numerous applications in the field of advanced material science and engineering due to their plentiful fascinating features. Following the first assembling of MPN films on diverse solid surfaces in 2013, MPN materials have attracted much attention in the membrane technology field to improve membrane multifunctionality through membrane surface or matrix modification for membrane structural stability, durability, and filtration efficiency enhancements. Moreover, the incorporation of inorganic nanomaterials, such as nanoparticles, nanotubes, nanorods, and nanosheets, and hydrophilic polymers, for instance, zwitterions and polyvinylpyrrolidone (PVP), can enable further improvements of MPN-based membranes for diverse water filtration applications. This review has critically summarized the recent MPN-based membrane modifications and identified areas that need to be considered in further research to enhance membrane durability, filtration performance, and operational lifetime. Overall, it is foreseen that the novel membranes, as well as an ever-widening scope of membrane applications based on the MPN material, will constantly emerge.

“…8 Among the commercially available NF membranes, polyamide (PA)-based composite NF membranes possessing a thin separation layer over an ultrafiltration support are the most popular ones because of their production feasibility and excellent separation perform-ance. 9−12 Despite the fact that the support membranes greatly affect the generation of the top PA film, 13 the natural features of the top PA film dominate the separation ability of the composite membrane. Therefore, precise regulation of the selective PA layer can be promising in expanding their applications.…”

Polyamide (PA) chemistry-based nanofiltration (NF) membranes have an important role in the field of seawater desalination and wastewater reclamation. Achieving an ultrathin and defect-free active layer via precisely controlled interfacial polymerization (IP) is an effective routine to improve the separation efficiencies of NF membranes. Herein, the morphologies and chemical structures of the thin-film composite (TFC) NF membranes were accurately regulated by tailoring the interfacial reaction temperature during the IP process. This strategy was achieved by controlling the temperature (−15, 5, 20, 35, and 50°) of the oil-phase solutions. The structural compositions, morphological variations, and separation features of the fabricated NF membranes were studied in detail. In addition, the formation mechanisms of the NF membranes featuring different PAs were also proposed and discussed. The temperature-assisted IP (TAIP) method greatly changed the compositions of the resultant PA membranes. A very smooth and thin PA film was obtained for the NF membranes fabricated at a low interfacial temperature; thus, a high 19.2 L m −2 h −1 bar −1 of water permeance and 97.7% of Na 2 SO 4 rejection were observed. With regard to the NF membranes obtained at a high interfacial temperature, a lower water permeance and higher salt rejection with fewer membrane defects were achieved. Impressively, the high interfacial temperature-assisted NF membranes exhibited uniform coffee-ring-like surface morphologies. The special surface-featured NF membrane showed superior separation for selected heavy metals. Rejections of 93.9%, 97.9%, and 87.7% for Cu 2+ , Mn 2+ , and Cd 2+ were observed with the optimized membrane. Three cycles of fouling tests indicated that NF membranes fabricated at low temperatures exhibited excellent antifouling behavior, whereas a high interface temperature contributed to the formation of NF membranes with high fouling tendency. This study provides an economical, facile, and universal TAIP strategy for tailoring the performances of TFC PA membranes for environmental water treatment.

Microporous membrane with a hydrophobic surface, high porosity, and narrow pore size distribution is the ideal membrane distillation (MD) membrane. The electrospun membranes for MD are a new type and effective way to seawater desalination. Herein, a novel polyvinylidene fluoride (PVDF)/tetrabutylammonium chloride (TBAC) electrospun nanofiber membrane (ENMs) fabricated apply to for direct contact membrane distillation (DCMD). Combine with the spinning condition, the characteristic and content of TBAC significant effect on the multimorphology structure of nanofiber. Therefore, the porous structure and morphology of PVDF/TBAC ENMs can be well-designed by optimizing relative humidity and TBAC concentration in spinning process, three different structure nanofiber membranes are obtained. Lab-scale setup is used to test membrane separation performance. The result indicates that the ultrafine ENMs with 0.025 mol L −1 TBAC presented a steady water flux of about 20.6 L m −2 h −1 and a high-efficiency salt rejection rate of over 99%. PVDF/TBAC ENMs are expected to provide a solution for development of efficient water treatment membrane.
