Polymer-Based Nanofibers: Preparation, Fabrication, and Applications

A comprehensive review on antimicrobial face masks: an emerging weapon in fighting pandemics

“…226 Most organic polymers, including natural polymers like chitosan, chitin, silk broin, dextran, collagen, alginate, gelatin, and synthetic polymers such as PS, PVC, PAN, PET, polyurethane, polyamide, are suitable for electrospinning. 227 Biocompatible and biodegradable polymers such as polylactic acid, poly lactic-co-glycolic acid, conductive polymers such as polyaniline, polypyrrole, and functional polymers as polyvinylidene uoride can also be electrospun. 223 Electrospinning technique can be employed to develop air ltration membranes and protective clothing materials with antimicrobial substances like metal NP, antibiotics, biopolymers, carbon nanomaterials, and natural compounds.…”

Electrospun Poly(ethylene Terephthalate)/Silk Fibroin Composite for Filtration Application

“…Electrospinning belongs among the most attractive methods for fabricating the fibrous membranes, which is a facile and effective approach for forming fine fibers in the micro- up to nanometers scale under the application of electric field [ 8 ]. Furthermore, this method offered the possibility to also prepare fibrous polymer products from synthetic or natural polymers or virgin and recycled polymers (plastic wastes) [ 9 , 10 , 11 ].…”

Nanofiber-based systems intended for diabetes

“…Viscosity and surface tension of polymer solution possess a decisive role in the morphology and size of electrospun NFs and are directly under the influence‫‬ of the molecular weight of polymer and solution concentration. Generally, low solution concentration that caused to low viscosity and high surface tension of the solution leads to the formation of beads and droplets, while very high solution concentration leads to blocking the capillary tip and disturbing rate of charged polymer flow leading to appear helix-shaped fibers and/or fibers could not be formed [47,48]. Besides, the molecular weight of polymer in a range suitable is necessary for the entanglement of polymer chains in solutions so that low molecular weight solutions resulted in the formation of beads instead of fibers and high molecular weight inclined to form microribbons [47,49].…”

“…A proper solvent is crucial for the dissolution of polymer and the formation of fibers during the electrospinning jet elongation through the evaporation of solvent and phase separation. Applying solvents with a higher evaporation rate and boiling point can lead to the generation of surface roughness and pores on the surface fiber [48,50]. The other important parameter, the solution conductivity is determined by types of polymer, solvent, and salt.…”
