Summary: Nanofiber membranes prepared by electrospinning technology have been considered as excellent candidates for air filtration, due to their high porosity, small pore size, and good connectivity. This review summarizes the recent research progress on electrospun nanofibers as air filters, including fabrication methods, filtration performances, advantages, and disadvantages. The prospects for using complex-structured nanofibers in air filtration are also discussed.

Summary: A polyurethane-based composite membrane with superhydrophilicity and high water flux was developed for the separation of micro- and nanoplastics as well as the adsorption of methylene blue dye. The membrane demonstrated selective adsorption for different-sized plastic particles and showed a maximum adsorption capacity for methylene blue dye. This study provides a new approach for the removal of micro- and nanoplastics and dyes from contaminated water.

Summary: In this study, a unique multi-scale nanofiber membrane prepared by electrospinning with the addition of tetrabutylammonium chloride (TBAC) was successfully applied as effective conductive fillers in Nafion membranes for proton exchange. The multi-scale nanofiber composite membranes showed improved proton conductivity and reduced methanol permeability, attributed to the hierarchical long-range channels for proton conducting and the hindrance of methanol penetration provided by the cross-linked nanofiber network. Additionally, the formation of effective acid-base pairs in the composite membrane facilitated proton hopping and enhanced proton conducting behavior.

Summary: Anion exchange membrane fuel cells (AEMFCs) have gained considerable attention in recent years. This study prepared and characterized polymer composite membranes composed of quaternary ammonium poly(vinyl alcohol) (QPVA) and poly(diallyldimethylammonium chloride) (PDDA). The influence of QPVA/PDDA mass ratios on the membranes and fuel cells was evaluated, and the best performance was achieved with the eQP-PDD0.5 membrane at 80 degrees C.

Summary: The study proposes electrospun nanofibrous polyimides enhanced with ion exchange properties as adsorptive membranes for dye-loaded textile wastewater treatment. By synthesizing carboxyl-functionalized porous polyimides and further decorating them with strong cation and anion exchange side groups, the membranes show promising potential in environmental applications. The results suggest that these membranes are promising candidates for the treatment of dye-laden wastewater due to their facile syntheses and unique properties.

Summary: In this study, hydrous manganese oxide (HMO) nanoparticles were successfully impregnated into polyacrylonitrile (PAN) nanofibers to obtain HMO-PAN composite electrospun nanofiber membranes (ENMs) via electrospinning technique. The composite ENMs showed strong adsorption capacity for lead (Pb(II)) and arsenic (As(V)) from aqueous solutions, with high Langmuir adsorption capacities. The material also exhibited excellent regeneration ability and retained a high percentage of adsorption capacity after multiple adsorption-desorption cycles, indicating its promising potential for long-term application.

Summary: This study investigates the influence of graphene oxide (GO) on the properties of electrospun recycled poly(ethylene terephthalate) (rPET) composite nanofiber membranes. Results show that GO loadings of less than 0.5 wt % lead to smoother fiber surfaces, enhancing hydrophilicity and crystallization performance. Ultimately, maintaining the GO content at a maximum of 0.5 wt % is preferable for maximizing hydrophilicity and filtration permeation flux in desired applications.
