“…Figure 1A schematically shows the pore size ranges of MF, UF, NF, and RO processes. Among the methods for fabrication of porous polymeric membranes, electrospinning is one of the easiest and most cost-efficient techniques to produce fibrous membranes with a wide range of fiber diameter and porosity for the filtration of polluted water, air, considering the ability for bactericidal activity and dye scavenging (Lv et al, 2018;Ma et al, 2019b). Although the electrospun fibrous membranes offer a highly porous non-woven structure, making them suitable for MF, UF, and even NF, they usually exhibit poor mechanical strength due to weak fiber-fiber connections via physical entanglements.…”

Among the different polymeric membranes, electrospun membranes have shown promising performance for filtration applications through the facile and controlled preparation method leading to tailored material structure. Furthermore, multilayered biobased electrospun membranes exhibited superior filtration performance, considering they are eco-friendly with superior mechanical properties and better adsorption efficiency compared to the single-layered electrospun membranes. The aim of this mini-review is to reveal the current state-of-art development of multilayered biobased electrospun membranes and to provide new insights into the future of tailored membranes toward practical applications.

“…The experimental results for MD with this dual-layered membrane, for a saline feed containing 1,000 ppm of oil yielded complete salt rejection. Ma et al (2019) worked on developing an oil-water separation technology which is energy-efficient. Superhydrophobic/ superoleophilic membranes based on a fluorine-free system were fabricated.…”

“…Materials with hydrophobic and oleophilic characters have potential to be used in processing the oil/water separation due to oil spills, an important environmental issue (15). In this regard, we need to mention that recently oil spills result in severe economic and environmental problems (16)(17)(18)(19). Moreover, the oil containing wastewater in the routine life is a big scientific challenge because of additional contaminants such as heavy metals and organic dyes (18).…”

“…Moreover, the oil containing wastewater in the routine life is a big scientific challenge because of additional contaminants such as heavy metals and organic dyes (18). Therefore, it is essential to find proper and efficient methods to solve this worldwide existing issue (17,19). Among different approaches in oil/water separation, membrane materials with differing interfacial characteristics of oils and water gain more interest (17).…”

Various aspects of electrospun fibers prepared from terpolymer of tetrafluoroethylene (TFE), hexafluoropropylene (HFP), and vinylidene fluoride (VDF) (THV)/acetone solutions at two applied voltages, THV/acetone solutions having Texas montmorillonite with two ratios, and THV/ethyl acetate solutions using two needle sizes are described. Fibers from THV/acetone and THV/ethyl acetate solutions showed shallow indentations and pores, respectively. The clay, functioning as electrospinning agent, did not influence the fiber morphology, but yielded narrower fiber diameter distribution and the thinnest fibers. Heterogeneous fiber diameter distribution and increase in the fiber diameters were observed by lowering the voltage for fibers of THV/acetone solutions. Fibers from THV/ethyl acetate solutions had the largest diameter and the broadest diameter distribution. Electrospun THV fibers having both hydrophobic characteristics with nearly 140° water contact angles and oleophilic properties with oil contact angles less than 45° might have applications in areas such as water/oil separation.
