“…For example, the URL understandingnano.com defines a nanofiber as a fiber with a diameter of 100 nanometers or less; the URL Wikipedia.org defines a nanofiber as a fiber with diameter in the nanometer range, while many publications on nanofibers range from 100 nm to less than 1000 nm. For an example, a recently published article by Qureshi et al. (2017) named nanofibers ranging from 100 to 300 nm.…”

The definition of a nanofiber is discussed, and the history of the development of bubble electrospinning is briefly elucidated, its main properties are emphasized, and the morphology of its products is summarized. A geometrical interpretation of the nanofiber membrane's adsorption is given as a natural intrinsic property of the geometrical potential of nanoscale structure. Nano-effect, Casimir effect, capillary effect, Earth's gravity difference, Newton's gravity, and lotus leaf's highly selective repulsion property can all be interpreted using the geometrical potential or boundary-induced force.

“…From the high resolution XPS of the C1 s in Figure c, it can be seen that C1 s peak at 285.8 eV of ACrFP was assigned to the COH/CN . In addition, both C1 s spectra of X‐3B‐ACrFP and K‐2BP‐ACrFP can be fitted to three peaks, which were assigned to CC/CC (284.7–284.8 eV), CO/CN (285.8–286.1 eV), and CO/CN (287.7–287.8 eV) . The appearance of these characteristic groups of reactive dyes in XPS spectra of X‐3B‐ACrFP and K‐2BP‐ACrFP confirmed the combination between dyes and ACrFP.…”

Amine resin (ACrFP) based on chromium (III)‐fibrous protein (CrFP) was synthesized by solvothermal reaction using tetraethylenepentamine, and its utilization in removing two kinds of anionic dyes (reactive brilliant red X‐3B and K‐2BP) was investigated. This adsorbent with protonated amine groups was characterized by SEM‐EDS, zeta potential, FTIR, Raman, and XPS. EDS analysis illustrated that the nitrogen content of ACrFP increased 6.40% compared with CrFP, suggesting grafting of amine groups into the framework of CrFP. Raman analysis of anionic dyes in solution and the ACrFP resin which has adsorbed dyes suggested that X‐3B and K‐2BP in solution have been loaded on solid, and XPS measurement of ACrFP, X‐3B‐ACrFP, and K‐2BP‐ACrFPfurther affirmed the results of Raman. Both sorption isotherms of X‐3B and K‐2BP were favored in lower temperature. About 0.1 mol/L of HCl could desorb reactive red dyes from ACrFP and the regenerated adsorbent could reuse several cycles. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S196–S204, 2019

The use of organic solvents for the preparation of nanofibers are challenged due to their volatile and hazardous behavior. Recently deep eutectic solvents (DES) are widely recognized as non-volatile and non-hazardous solvents which never been utilized directly for nanofabrication via electrospinning. Here, we present the preparation of Zein nanofibers using deep eutectic solvents (DES-Zein). The DES-Zein nanofibers were produced at an optimized polymer concentration of 45% (w/w) with pH 7.3 and electroconductivity 233 mS cm−1. DES-Zein nanofibers showed aligned to tweed like cedar leaf morphology tuned by varying the spreading angle from 0° to 90°. In contrast to hydrophobic conventional Zein nanofibers, DES-Zein nanofibers showed super hydrophilic character and about 200 nm finer average diameter. The proposed method of preparing Zein nanofibers using DES opens a new door to continuous electrospinning with tunable morphology, having potential to be used for environmental and biomedical applications.
