“…A number of hydrophobic polymers have been investigated for organophilic pervaporation, including poly(dimethylsiloxane) (PDMS) [9], poly(octylmethyl siloxane) (POMS) [10][11][12], polyvinylidene fluoride (PVDF) [13], polyether-block-polyamide (PEBA) [14], poly(1-trimethylsilyl-1-propyne) (PTMSP) [15] and the polymer of intrinsic microporosity PIM-1 [16][17][18][19]. Inorganic membrane materials such as silicalite-1 [20] have also been employed.…”

Membranes that enable the recovery of organic compounds from dilute aqueous solution are desired for applications such as biobutanol production. The polymer of intrinsic microporosity PIM-1 shows promise for organophilic separations and here it is incorporated into thin film composite (TFC) membranes in order to increase the flux of permeate. Asymmetric polyvinylidene fluoride (PVDF) supports were prepared with pore sizes at the surface in the size range 25-55 nm and fractional surface porosities in the range 0.38-0.69, as determined by atomic force microscopy (AFM). The addition of phosphoric acid to the PVDF dope solution helped to control the pore size and porosity. Supports were coated with PIM-1 to form TFC membranes with active layer thicknesses in the range 1.0-2.9 m. Membranes were tested for the pervaporation of a 1-butanol/water mixture (5 wt.%). At 65 C, values of total flux up to 9 kg m-2 h-1 were obtained, with separation factors up to 18.5 and values of pervaporation separation index (PSI) up to 112 kg m 2 h 1 .

“…Correspondingly, hydrophilic pervaporation membranes are favorable to this application owing to their selective transport of polar water molecules [ 379 ]. Other aspects of pervaporation applications, such as solvent recovery from organic-organic [ 380 , 381 , 382 ] and organic-water mixtures [ 199 , 383 , 384 , 385 , 386 , 387 , 388 , 389 , 390 ] and the removal of volatile organic compounds from wastewater [ 391 , 392 , 393 , 394 ] using hydrophobic membranes, have been well-reported.…”

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.

“…3d, the performance of ÂSPAES membrane for n-BuOH is compared to the state-of-the-art membranes reported in the literature with a binary mixture. 22,25,[35][36][37][38][39][40][41][42][43][44] The pervaporation membranes typically show high n-BuOH flux with average selectivity less than 100 (Table S2, ESI †). Considering the conventional fed-batch fermentation cannot produce higher than 1.2 wt% concentration of n-BuOH, the n-BuOH aqueous solution at a condenser achievable by the state-of-the-art membranes is at maximum B50 wt%.…”
