“…Not all the stationary spinnerets are suitable for the upward e‐spinning. The spinnerets like flat electrode with holes, tube with linear holes, and conical wire coil, always take the form of downward e‐spinning with the fiber collector right below the spinnerets. Figure lists the stationary spinnerets for downward e‐spinning.…”

“…However, the significance of multihole e‐spinning study is that the electric field can be kept uniform when the number of holes increased, which is different from the complex electric field of the multineedle e‐spinning . For example, Zheng et al made a comparison between 7‐hole spinneret and 7‐needle spinneret . Experimental results showed that 7‐hole e‐spinning system obtains lower jet divergence degree and smaller jet whipping amplitude than those in the 7‐needle system (Figure c,d), which results in more concentrated and smaller fiber mats on the collector.…”

Electrospinning (e-spinning) has been extensively explored as a simple, versatile, and cost-effective method in preparing ultrathin fibers from a wide variety of materials. Electrospun (e-spun) ultrathin fibers are now widely used in tissue scaffold, wound dressing, energy harvesting and storage, environment engineering, catalyst, and textile. However, compared with conventional fiber industry, one major challenge associated with e-spinning technology is its production rate. Over the last decade, compared with conventional needle e-spinning, needleless e-spinning has emerged as the most efficient strategy for large-scale production of ultrathin fibers. For example, rolling cylinder and stationary wire as spinnerets have been commercialized successfully for significantly improving throughput of e-spun fibers. The significant advancements in needleless e-spinning approaches, including spinneret structures, productivity, and fiber quality are reviewed. In addition, some striking examples of innovative device designs toward higher throughput, as well as available industrial-scale equipment and commercial applications in the market are highlighted.

“…Moreover, the confined feeding method can produce fibers of special structures, such as core‐shell fibers. Our previous work developed a multihole system with a flat spinneret to scale up the productivity of electrospun nanofibers. We found that this multihole system created a more uniform electric field than the conventional multineedle system.…”

An approach to the scale‐up of co‐electrospinning via a flat core‐shell structure spinneret has been developed in this study. The spinneret with a flat surface involves shell‐holes and core‐needles. Electric field simulation reveals that the flat core‐shell spinneret configuration creates a more uniform electric field gradient. Experimental study shows that in comparison with the conventional needle co‐electrospinning, core‐shell nanofibers produced by this new designed setup are finer and of better morphology. Composite nanofibers with special morphologies can be fabricated by modifying the structure of this spinneret. The production rate of the core‐shell nanofibers can be enhanced by increasing the hole and needle number of the spinneret. This novel design is expected to provide a promising method towards the massive production of core‐shell nanofibers. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 41027.

Among currently available nanostructured materials, ultrafine nanofibers, carrying a range of novel physical and chemical properties, have attracted considerable attention in overcoming many limitations present in their corresponding macroscales. [14][15][16][17][18][19] Different strategies have been created and developed for nanofibers fabrication, including thermal-induced phase separation, drawing, template synthesis, and self-assembly, among which electrospinning is of considerable significance as a rapid, simple, and continuous process in manufacturing nanofibers, as well as formulating their 2D and 3D structures. [20][21][22][23][24][25][26] Besides, this straightforward, continuous, and cost-effective method can launch ultrathin nanofibers from an enormous number of materials, including polymers, inorganic ceramics, and composites. [27][28][29][30][31][32] Moreover, electrospun nanofibers and their assemblies are much more favorable in providing high specific surface area, large surface-to-volume ratio, tunable porosity with uniform pores distribution, and the ability of desired chemical functionalization for various applications. [33][34][35][36][37][38][39][40] This review aims to provide comprehensive and critical aspects related to recent developments in electrospinning Electrospinning, considered as a low-cost and straightforward approach, attracts tremendous attention because nanofibrous materials with functional properties prepared by it can be widely applied in numerous fields, including rechargeable batteries, filtration, and distillation.

Afterward, the corresponding properties of electrospun nanofibers are discussed. A future vision regarding challenges and perspectives in this area is proposed at the end. It is believed that this review would provide an extensive and comprehensive reference to utilize this advanced technique to generate novel nanofibers performing in high demanding areas.
