“…In this section, the focus is on applications of ion‐exchange nanofibers in the environment and energy fields; separation/purification processes and fuel cells. It should be noted that the application of ion‐exchange nanofibers in catalysts for chemical processes and biotechnologies including drug delivery systems and scaffolds for tissue engineering, are beyond the scope of this review.…”

Nanofibers have unique functionalities based on their nanoscaled cross‐section, high specific surface area, and high molecular orientation inside the fibers. These functionalities can be improved by controlling their diameter, surface and internal structures. The introduction of ion‐exchange sites on the surface and/or inside the nanofibers provides novel high‐functional ion‐exchangers with high surface areas, high ion‐exchange and adsorption capacities, and high ionic conductivities. The present review highlights the fundamental aspects of ion‐exchange nanofibers (i.e. their size‐dependent unique properties and production methods) and their recent advances in the environment and energy applications (i.e. separation/purification processes and fuel cells). © 2018 Society of Chemical Industry

“…Recent studies have focused on using this technique for various applications, such as with affinity membranes, for drug release, tissue scaffolds, sensors, as protective clothing agents, and in the fields of energy, electronic devices, and composite reinforcement [ 1 , 2 , 3 , 4 , 5 , 6 ], mainly because of the remarkable properties of electrospun nanofibers, such as a small diameter, high aspect ratio, large specific surface area, and unique physical and chemical properties [7] . The polymers commonly used for fabricating the electrospun nanofiber membrane are polyvinylidene fluoride (PVDF) [8] , polysulfone (PSU) [9] , polyacrylonitrile (PAN) [10] , polyethersulfone [11] , polyamide (PA) [12] , and polyvinyl alcohol (PVA) [ 13 , 14 , 15 , 16 ].…”

Electrospun nanofibers of polyvinyl alcohol (PVA) have poor mechanical strength. As such their use has often been avoided, particularly in applications that require high mechanical properties. The objective of this study is to increase the mechanical properties of PVA nanofiber mats via physical crosslinking with solvent vapor treatment using organic solvents, dimethyl sulfoxide (DMSO), N, N-dimethyl formamide (DMF), and methanol. The effect of solvent vapor treatment on PVA nanofibers is clearly observed by scanning electron microscope (SEM). The tensile strength increased by over 60%, 90%, and 115% after solvent vapor treatment with DMF at a temperature of 40 °C for 2 h, 4 h, and 8 h, respectively, compared to untreated PVA nanofibers. In addition, Young's modulus of PVA nanofiber mats also increased after DMF treatment. As a comparison, DMSO and methanol were also used in solvent vapor treatment because of differences in their polymer-solvent affinity. Results showed that the highest improvement (100%) in mechanical strength was obtained using DMF. This study shows that solvent vapor treatment offers a simple and inexpensive method that provides excellent results and is a promising alternative treatment for use in increasing the mechanical properties of electrospun nanofibers.

“…Electrospinning is well documented and is considered an easy laboratory method for producing submicron and nanofibers [12,13]. Electrospun polymer fibers are widely used in filtration [14,15], catalysis [16][17][18][19][20][21][22], biomedical materials [23][24][25][26], and electrolytes [7,27].…”

Electrospun polymeric nanofibers with flexible three-dimensional porous structures and high surface-to-volume ratio are potential resources for several novel applications in the fields of micro-and nanoscale filtration, water desalination, drug delivery, life sciences, catalysis, and energy harvesters. Functionalized polymeric fibers with enhanced molecular orientation, surface textural morphologies, and piezo-, pyro-, and ferroelectric properties are of technical and commercial interest around the world. Several emerging technologies including electrical polarization, vacuum plasma treatment, corona discharge, surface fluorination, and chemical treatments to functionalize the polyvinylidene fluoride nanofibers are discussed as potential applications of electroactive materials.
