“…The failure of EA to produce nanofibers is because of its deficient spinnability (viscoelastic property). These results were similar to those reported by Wongsasulak et al 21 However, their EA solutions gelled beyond 5%, unlike the EA solutions we used, which were stable up to 20%. The observed difference may be attributed to the difference in EA molecular weights and the concentration of formic acid.…”

“…The solution conductivity of various polymers and blends was recorded using a conductivity electrode at 25 1C. According to earlier findings, 21 and as explained above, our studies also revealed increases in viscosity and conductivity (viscosity is inversely proportional to surface tension) with increased pure EA content from 8 to 25%; thus, we expected nanofiber formation (Table 1). However, our experiments proved that pure EA protein was unable to produce nanofibers; even though the protein had sufficient polymer concentration, viscosity, conductivity and surface tension, it lacked viscoelastic properties.…”

“…2,5 Accordingly, formic acid was identified as a good organic solvent for various protein polymers to produce nanofibers because formic acid is more volatile than water. 21,[30][31][32][33][34][35] Furthermore, formic acid is also considered non-toxic and is used in edible chitosan films. 36 The solution viscosity for globular proteins is reported to be higher in formic acid than in water 35 because of the unfolding and swelling of globular proteins.…”

Wongsasulak et al 21 have studied the electrospinning of egg albumen (EA)-polyethylene oxide and clearly explained the influence of polyethylene oxide in the development of nanofibers and their physical and thermal properties.…”

Egg albumen (EA), a highly functional globular protein with desirable properties, is the least-explored material for biomaterial applications, although it is available in abundance. In our studies, we explored the viability of EA and various blends with biocompatible and non-toxic poly (vinyl alcohol) (PVA) to produce nanofibers for biomedical applications. EA and PVA blends were prepared in various compositions. Electrospinning was used to fabricate non-woven nanofibers. Solution properties, such as viscosity and electrical conductivity, were evaluated for various prepared solutions. Solution viscosity increased with increasing polymer concentration. Solutions with higher contents of EA recorded increased conductivity, which decreased with increasing PVA content. The influence of solution properties on the morphological appearance of as-spun products was studied using scanning electron microscopy. Instead of nanofibers, nanoparticles and microparticles of EA were produced at even higher contents. In contrast, a gradual increase in the addition of PVA content to 8% EA solution resulted in the transformation of particles from large agglomerates to very fine fibers (E100 nm in diameter) because of the influence of polymer content, viscosity and conductivity. The polymer-polymer interactions in the prepared materials have been validated by Fourier transform infrared spectroscopy, differential scanning calorimetry, X-ray diffraction and gel electrophoresis.

“…The increase in viscosity is attributed to the increased molecular entanglement between the TiO 2 sol and PVAc solution during the process of mixture. 9 SEM images present the fibrous structures of the electrospun nanofibers, but the SEM images obtained fail to show distinguishable TiO 2 domain in the PVAc/TiO 2 hybrid nanofibers. The AFM and TEM observations were also used in this work to obtain more details on the surface morphology and bulk structures of the hybrid nanofibers.…”

Polyvinyl acetate (PVAc)/titanium dioxide (TiO 2 ) hybrid nanofibers were fabricated by combining sol-gel process with electrospinning technology, which consisted of PVAc as organic segment and TiO 2 as inorganic part. The surface structures of the PVAc/TiO 2 hybrid nanofibrous mats were examined using scanning electron microscopy (SEM). The surface morphology and bulk structures of single nanofiber were investigated by atomic force microscopy (AFM) and transmission electron microscopy (TEM). Fourier transform infrared spectroscopy (FTIR) was employed to analyze the chemical structures of the PVAc/TiO 2 hybrid nanofibers. SEM scanning revealed that the fibrous structure was formed. AFM observations presented a significant difference in the morphology of the nanofibers before and after hybridization. It was observed from TEM images that some black streaks with various lengths distributed in a nanofiber. The FTIR analysis indicated the newly formed associated hydrogen bond because of the hybrid effect between PVAc and TiO 2 sol.

Interpenetrating‐Syncretic Micro‐Nano Hierarchy Fibers for Effective Fine Particle Capture

et al. 2019

In nature, valuable and essential multilevel hierarchy structures are common in microstructures and macrostructures. Researchers try to emulate these unique structures or obtain inspiration from them. In general, materials with a single structure are easy to prepare but it is difficult to achieve multiple functions or performances simultaneously. Here, a facile method with general applicability and a high yield for preparing interpenetrating‐syncretic micro‐nanocomposite fibers with a multilevel hierarchy structure via bicomponent electrostatic‐centrifugal spinning is introduced. This 3D structure is distinctive and differs from previous micro‐nanocomposite structure, in which nanofibers are embedded through microfibers. The formation of a longer, more complex and diversified path is close to undulating surface, mainly because of microfiber introduction. Those characteristics in favor of improving the capture rate of particle on the surface. Two different preparation routes are designed. By controlling the spinning parameters, samples with an outstanding filtering efficiency, a low pressure drop, a high quality factor, an optical transparency, and an excellent impact resistant are constructed. Because the different fiber diameters assume different functions, this work could be used to construct diverse materials by using suitable polymers in other fields that require different fiber sizes and a solid multilevel hierarchy structure to improve the mechanical properties and corresponding performance.
