“…In addition to chitosan, other positively charged NFs are being investigated as heavy metal adsorbents. Zeytuncu et al prepared PVA/(maleic anhydride)/acryloyl thioamide monomer NF mats using a combination of electrospinning and UV irradiation [40]. The mats revealed a maximum adsorption of 69.…”

The unique functions of nanofibers (NFs) are based on their nanoscale cross-section, high specific surface area, and high molecular orientation, and/or their confined polymer chains inside the fibers. The introduction of ion-exchange (IEX) groups on the surface and/or inside the NFs provides de novo ion-exchangers. In particular, the combination of large surface areas and ionizable groups in the IEX-NFs improves their performance through indices such as extremely rapid ion-exchange kinetics and high ion-exchange capacities. In reality, the membranes based on ion-exchange NFs exhibit superior properties such as high catalytic efficiency, high ion-exchange and adsorption capacities, and high ionic conductivities. The present review highlights the fundamental aspects of IEX-NFs (i.e., their unique size-dependent properties), scalable production methods, and the recent advancements in their applications in catalysis, separation/adsorption processes, and fuel cells, as well as the future perspectives and endeavors of NF-based IEMs.

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

“…In this study, different approaches were used for crosslinking of PCLF:PCL nanofibers. Recently, in situ photo‐crosslinking has been used for crosslinking of different polymers such as gelatin, poly(vinyl alcohol), methacrylated polycarbonate and hybrids of polyurethane/methacrylated poly(ethylene glycol) during electrospinning . In the mentioned studies, the methacrylate group was activated when exposed to light, and by creating crosslinking bonds (with opening of double carbon bonds) produced from elastomeric properties in fabricated nanofibers.…”

“…Recently, in situ photo-crosslinking has been used for crosslinking of different polymers such as gelatin, poly(vinyl alcohol), methacrylated polycarbonate and hybrids of polyurethane/methacrylated poly(ethylene glycol) during electrospinning. [35][36][37][38] In the mentioned studies, the methacrylate group was activated when exposed to light, and by creating crosslinking bonds (with opening of double carbon bonds) produced from elastomeric properties in fabricated nanofibers. Since the mechanism for creating crosslinking bonds by the fumaryl group is similar to methacrylate, in situ photo-crosslinking was examined for crosslinking of PCLF in this research and results (mechanical properties and dissolution test) showed that no crosslinking was occurred in the structure of nanofibers.…”

“…Since the mechanism for creating crosslinking bonds by the fumaryl group is similar to methacrylate, in situ photo-crosslinking was examined for crosslinking of PCLF in this research and results (mechanical properties and dissolution test) showed that no crosslinking was occurred in the structure of nanofibers. It should be noted that in the previous studies the crosslinking of PCLF was performed by exposing of PCLF solution to UV radiation [35][36][37] while during electrospinning, the nanofibers solidify immediately. Moreover, the crosslinking reaction of fumarate-based macromeres is very slow due to the steric hindrances constrained from the fumarate double bonds that positioned with their arms as trans isomer along with the PCLF backbone that restrict the movement of the macroradicals generated by the PCLF chains.…”

With regard to flexibility and strength properties requirements of soft biological tissue, elastomeric materials could be more beneficial in soft tissue engineering applications. The present work investigates the use of an elastic polymer, (polycaprolactone fumarate [PCLF]), for fabricating an electrospun scaffold. PCLF with number-average molecular weight of 13,284 g/mol was synthetized, electrospun PCLF:polycaprolactone (PCL) (70:30) nanofibrous scaffolds were fabricated and a novel strategy (in situ photo-crosslinking along with wet electrospinning) was applied for crosslinking of PCLF in the structure of PCLF:PCL nanofibers was presented. Sol fraction results, Fourier-transform infrared spectroscopy, and mechanical tests confirmed occurrence of crosslinking reaction. Strain at break and Young's modulus of crosslinked PCLF:PCL nanofibers fabricated was found to be 114.5 ± 3.9% and 0.6 ± 0.1 MPa, respectively, and dynamic mechanical analysis results revealed elasticity of nanofibers. MTS assay showed biocompatibility of PCLF:PCL (70:30) nanofibrous scaffolds. Our overall results showed that electrospun PCLF:PCL nanofibrous scaffold could be considered as a candidate for further in vitro and in vivo experiments and its application for engineering of soft tissues subjected to in vivo cyclic mechanical stresses. © 2017 Wiley Periodicals, Inc.
