“…Nanofibers obtained from a polymer solution by electrospinning are collected in the electromagnetic field as a network of randomly arranged continuous fibers. Nanofiber yarn production can also be carried out in an electrospinning device on a similar principle, but with collecting surfaces of various shapes for yarn formation 11–13 . These methods can be diversified as yarn twisting by rotating the collector unit, wet spinning, texturing, air twisting machine, spinning with twist tubes, and so forth.…”

Today a wide variety of wearable electronics are in our daily lives and their uses are increasing. The development of portable, flexible, lightweight, cost‐effective, and stable devices that produce sustainable energy with renewable approaches in the field of wearable electronics, as in every field, is one of the important issues of today. According to their volume and weight, the use of nanofibers with high surface area in energy‐generating devices may bring them advantages such as lightness and higher energy density. Therefore, in recent years, researchers have focused on the development of nanofiber‐based nanogenerators that produce energy using mechanical energy in a sustainable and renewable way. In this paper, self‐standing piezoelectric nanogenerator (PENG) fabrics were obtained by developing flexible composite poly(vinylidene fluoride) (PVDF) nanofiber yarns doped with zinc oxide (ZnO) nanoparticles at different rates to provide higher power output. It has been characterized from electromechanical, structural, and morphological aspects. The most successful self‐standing PENG fabric obtained (at 5% ZnO loading) doubled the energy output of the fabric made from pure PVDF nanofiber yarn and provided a peak total power of 81 μW and a power density of 30 μW/cm2. The present results open up the field for the development of PVDF/ZnO‐based nanomats and their use in sensors and actuators in the healthcare and engineering industries.

“…In addition to the material from which the collector is produced, its geometry also affects the nanofiber morphology [31]. The effect of collector thickness and material was also studied by using collectors in square form at different thicknesses and materials in general [32]. More recently, not in nanofibrous production but nanofiber production, four different types of conical aluminum collector was used for nanofiber yarn production in electrospinning showing that fibers in electrospun yarn becomes finer as collector thickness increases [33].…”

The aim of this study is to examine the morphological properties of fibers produced by using metal plates of different thickness and materials as collectors in electrospinning. For this, circular shaped aluminum and copper plates of 1 mm, 5 mm, 10 mm thickness were used. The results show that much finer fibers were obtained when copper collectors are used compared to aluminum collectors. When the effect of collector thickness is analyzed, it was observed that fiber fineness increased as the collector thickness increased. In addition, it was observed that collection area of fibers on collector is much larger when aluminum collector and thinner collector is used showing that collector material and collector thickness affect fiber arrangement and interfiber spacing in electrospinning. A theoretical approach is also included in this work regarding effect of collector thickness and collector material type together with its verification in the light of experimental results.

The electrospun yarn for sutures has gained worldwide attention due to its fine fibers that resemble the extracellular matrix and its abundant functional sites. However, the use of a large number of toxic solvents poses safety risks and environmental pollution during production, making it challenging to directly apply electrospun yarn in the biomedical field. In this study, an environmentally friendly and safe method without toxic solvents was proposed for preparing antibacterial PLA ultrafine fiber sutures. This method involves melt electrospinning, hot‐stretching, low‐temperature plasma treatment, and chitosan grafting. The PLA ultrafine fiber sutures exhibit a high tensile strength which is 2.04 N before knotting and 1.57 N after knotting. The suture diameter is 118.7 μm and average fiber diameter is 1.72 μm. Chitosan grafted on the fiber surface provides excellent antibacterial properties for the sutures, with antibacterial rates against Escherichia coli and Staphylococcus aureus reaching 99.89% and 99.11%, respectively. The cell survival rate is 97.33%, while hemolysis rate is only 2.35%, demonstrating excellent biocompatibility of PLA ultrafine fiber sutures. This study presents a green and safe method for preparing clinically applicable absorbable antibacterial surgical sutures with high mechanical properties.Highlights A green and safe method for preparing PLA‐CS ultrafine fiber sutures. PLA‐CS suture with a tensile strength of 2.04 N and a fiber diameter of 1.72 μm. PLA‐CS suture with good antibacterial property and biocompatibility.
