“…Some researchers explored the green preparation methods to prepare HF OSN MMMs. Kato et al [ 61 ] spun polyamide 6 HF OSN MMMs containing delaminated layered montmorillonite nano-fillers in one step via TIPS process without crosslinking step. Compared with their previous work [ 33 ], inorganic nano-fillers improved the thermoplasticity and crystallinity of polyamide 6, thus further enhancing the stability of the prepared HF OSN membranes.…”

“…Incorporation of nanomaterials into the substrate to prepare HF OSN MMMs has been proven to be an effective integral modification method [ 59 , 60 , 61 ]. The introduction of nanofillers effectively enhances the OSN performance of HF OSN membranes, but the defect-free preparation of MMMs is still challenging because the agglomeration of nanofillers is general during the preparing process of MMMs [ 21 ].…”

“…One strategy to change the surface properties or morphology of the prepared membranes is the introduction of nanomaterials [ 15 , 59 , 60 , 61 , 67 ]. The work of Prof. Su [ 15 ] showed that the permeance of HF OSN membrane increased by 65% after doping with GO meanwhile maintaining the high solute rejection.…”

“…Many types of polymer materials have been used to fabricate HF OSN membranes, including PI [ 15 , 28 ], PAN [ 47 , 48 ], PBI [ 19 , 54 ], PA [ 52 , 61 ], PPTA [ 32 ], PVDF [ 18 ], polyetherimide [ 67 , 86 ], PAI [ 31 , 42 ], PPSU [ 43 ], PANi [ 44 ], and polypropylene [ 77 ]. PI is the most widely used polymer to prepare OSN membranes because of its good heat resistance, chemical stability, easy processing, etc.…”

Organic solvents take up 80% of the total chemicals used in pharmaceutical and related industries, while their reuse rate is less than 50%. Traditional solvent treatment methods such as distillation and evaporation have many disadvantages such as high cost, environmental unfriendliness, and difficulty in recovering heat-sensitive, high-value molecules. Organic solvent nanofiltration (OSN) has been a prevalent research topic for the separation and purification of organic solvent systems since the beginning of this century with the benefits of no-phase change, high operational flexibility, low cost, as well as environmental friendliness. Especially, hollow fiber (HF) OSN membranes have gained a lot of attention due to their high packing density and easy scale-up as compared with flat-sheet OSN membranes. This paper critically reviewed the recent research progress in the preparation of HF OSN membranes with high performance, including different materials, preparation methods, and modification treatments. This paper also predicts the future direction of HF OSN membrane development.

“…OSN is able to separate organic solvents and solutes larger than 200 Da. 4,8,9 OSN research has developed rapidly since its inception, enabling the separation of peptides, 10 dyes, 11 catalysts, 12 and pharmaceutical intermediates 13 in organic solvents. OSRO was developed to separate smaller molecular sized solutes, allowing separation of organic solvent mixtures.…”

This study investigates the recycling of polyamide 6 (PA 6) wastes to produce nonwoven fabrics based on nanofibers (PA‐NWNF) to promote sustainable textile solid waste management and generate a novel material with exceptional properties. PA‐NWNF characteristics can be controlled by adjusting the electrospinning parameters. A comprehensive characterization will be performed using various analytical techniques, such as scanning electron microscopy (SEM), Fourier‐transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), Brunauer–Emmett–Teller (BET), and dynamic mechanical analysis (DMA), to evaluate the unique properties as a function of the electrospinning parameters. According to the SEM results, concentrations of 21% are suitable to produce nanofiber with a well‐defined morphology, provided that the applied voltage is maintained at 20 kV and the collecting distance is above 10 cm, irrespective of the flow rate in the established protocol. XRD and FTIR analysis indicate a gradual decrease in the α‐phase and a simultaneous increase in the γ‐phase as the solution concentration increases. Moreover, low applied voltage favored β‐form crystallization over γ and α‐forms predominant at the higher voltage. DMA and BET data reveal that the elongated droplets formed at lower concentration exhibit a low storage modulus, high damping factor, highest surface area, and smallest pore diameters.
