“…Zaarour et al 70 studied the oil absorption capacity of PVDF sorbent based on the branched structure. This sorbent showed an outstanding oil absorption capacity of 93 ± 3.2 g/g, 122 ± 7.3 g/g, and 149 ± 10.1 g/g for olive oil, motor oil, and silicon oil, respectively, owing to its high specific surface area (Figure 17).…”

“…The branched TiO 2 /carbon nanofibers' electrode delivers a stable capacity of 283.5 mAh g À1 at a current density of 200 mA g À1 after 1000 cycles and can still achieve 204.1 mAh g À1 even when the current density is raised to a very high rate of 2000 mA g À1 (Figure 19). They found that the free-standing hierarchically branched TiO 2 /carbon 70 nanofibers can be served as anode materials for sodium-ion batteries (SIBs) and some other flexible electronic devices.…”

Engineering surface morphologies of nanofibers has been attracting significant consideration in numerous fields and applications. Among different methods of generating nanofibers, electrospinning is the most widely adopted technique owing to the ease of forming nanofibers with an extensive range of properties and its exceptional advantages, such as the variety of shapes and sizes, as well as the adaptable porosity of nanofiber webs. The branched structure is considered one of the most attractive structures for scientific researchers due to its outstanding properties (e.g., high-specific surface area and extremely tiny diameters of branched nanofibers). Therefore, this work is the first one that summarizes the strategies and methods, reported so far, of producing branched nanofibers of different materials. The material types, formation mechanisms, characterizations, and applications of the branched nanofibers generated through different techniques will be discussed in detail in this study. We believe this work can be served as an important reference for the preparations, strategies, and applications of the branched nanofibers.

The effects of morphology, defects and polymer concentration on nonlinear absorption characteristics of electrospun polyamide 6 (PA 6) nanofibers were studied systematically. Scanning electron microscopy measurements showed that a deviation from uniform nanofibers to irregular cob-web nanofibers morphology occurred with increasing PA 6 concentration and fiber diameter. Open aperture Z-scan results indicated that the thinner uniform PA 6 nanofibers present higher nonlinear absorption. This observation is mainly attributed to a greatest light scattering for thicker uniform nanofibers, considering the linear optical analysis of the PA 6 nanofibers. As a secondary factor, this could be associated with defect state distribution within the band gap, which facilitates the contribution of two photon absorption (TPA) and free carrier absorption (FCA) to nonlinear absorption. Moreover, the thinner uniform nanofibers exhibit higher optical limiting behavior. Polyamide 6 nanofibers attract more attention for biomedical applications due to their good biocompatibility. However, to our knowledge, no study exists on PA 6 nanofibers nonlinear optical properties and their dependency on nanofiber morphology. Therefore, in line with the reported results, this report reveals that PA 6 nanofibers are a promising material for optoelectronic applications as well as biomedical applications.

Novel photochromic and long‐persistent photoluminescent electrospun nanofibrous films were developed for anticounterfeiting applications. The inclusion of rare‐earth activated strontium aluminum oxide (RSAO) nano‐scaled particles into nanofibers of cellulose acetate‐polycaprolactone (CA‐PCL) composite facilitated the development of a simple method for creating an organic–inorganic photoluminescent nanocomposite. Upon excitation at 365 nm, the luminescent nanofibrous films showed an emission band of 516 nm. The current from photochromic films change color to green when illuminated with ultraviolet light as proved by absorption and fluorescence analyses, and CIE Lab parameters. Both mechanical and hydrophobic properties of the electrospun films were found to improve with raising RSAO content in CA‐PCL. Improved hydrophobic performance was monitored without any compromise to their other desirable properties. The morphology of the synthesized phosphor nanoparticles was investigated to indicate particle diameter of 2–12 nm, whereas the morphology of the electrospun nanofibers displayed diameters of 200–300 nm. The cytotoxicity of RSAO was also explored using the MTT proliferation assay. When exposed to UV, the nanofibrous films showed reversible photochromism without fatigue
