“…The formation of this secondary surface morphology is attributed to the fast solvent evaporation (dichloromethane) at the early stage of electrospinning, followed by phase separation and the creation of tiny holes on the fiber surfaces. After the elongation and solidification of the polymer jet, the created voids turned themselves into grooves and wrinkles on the fiber surfaces [ 32 ]. On the contrary, at 12% of the polymer blend, uniform fibers with a smooth surface were obtained.…”

The essential oil from Zingiber cassumunar Roxb. (Plai) has long been used in Thai herbal remedies to treat inflammation, pains, sprains, and wounds. It was therefore loaded into an electrospun fibrous membrane for use as an analgesic and antibacterial dressing for wound care. The polymer blend between poly(lactic acid) and poly(ethylene oxide) was selected as the material of choice because its wettability can be easily tuned by changing the blend ratio. Increasing the hydrophilicity and water uptake ability of the material while retaining its structural integrity and porosity provides moisture balance and removes excess exudates, thereby promoting wound healing. The effect of the blend ratio on the fiber morphology and wettability was investigated using scanning electron microscopy (SEM) and contact angle measurement, respectively. The structural determination of the prepared membranes was conducted using Fourier-transform infrared spectroscopy (FTIR). The release behavior of (E)-1-(3,4-dimethoxyphenyl) butadiene (DMPBD), a marker molecule with potent anti-inflammatory activity from the fiber blend, showed a controlled release characteristic. The essential oil-loaded electrospun membrane also showed antibacterial activity against S. aureus and E. coli. It also exhibited no toxicity to both human fibroblast and keratinocyte cells, suggesting that the prepared material is suitable for wound dressing application.

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.

Structures modification of fibers has been attracting significant attention in various fields and applications. Among different techniques of fabricating ultrathin fibers, electrospinning is the most commonly adopted method because of the ease of forming fibers with a wide range of properties and its exceptional advantages, such as the ability to spin into different shapes and sizes, as well as the adaptable porosity of electrospun fiber webs. The crimped structure has been attracting the attention of scientific researchers owing to its unique properties (eg, spring-like behavior, supreme strain, remarkable specific surface area, good piezoelectric properties, excellent biological properties, and so on). Therefore, this study summarizes a review of the strategies and methods, reported so far, of generating electrospun crimped ultrathin fibers of various polymers. The review focuses on the polymer types, formation methods, characterizations, and applications of the electrospun crimped ultrathin fibers. We believe this work can serve as an important reference for the materials, strategies, and applications of crimped fibers.
