Recently developed electrospinning methods: a review

Abstract

Conventional electrospinning is an effective and versatile method employed for fabricating nanofibers. However, the relatively low production rate is the major challenge of electrospinning as an economic and scalable method. Recently, several approaches have been developed to ensure the high production rate of nanofibers. This paper has reviewed the latest developed electrospinning methods, such as multi-jet, needleless, bubble, centrifuge and electro-centrifuge systems. Furthermore, the jet formation in centrifugal spinning, as well as electro-centrifuge systems, was investigated through experimental and numerical analysis.

Morphology evolution of self‐same nanocomposites hybridized with jumbo‐sized particles

“…The settings at which bead‐free and homogenous nanofibers were fabricated are shown in Figure 2e,i–k,m,n. Among these combinations, when the feed rate was set to 0.2 ml/h and applied high voltage to 16 kV (Figure 2e), a multi‐jet formation 48 was observed (inset of Figure 2e). In contrast, when the feed rate was set to 0.6 ml/h and applied voltage to 12 kV (Figure 2k), the suspension droplet 49 grew substantially on the nozzle tip after a few minutes (inset of Figure 2k).…”

Rational Design of Advanced Triboelectric Materials for Energy Harvesting and Emerging Applications

“…Typical examples include PVDF doped with silver nanowires (AgNWs), which enhances the potential of the friction layer, poly(ε-caprolactone) (PCL) doped with GO, which increases the surface charge density, and PVDF doped with Fe 3 O 4 , which improves the magnetic properties. [67] So, the methods and applications of doping nanomaterials in electrospun triboelectric materials are also described in detail in Section 3.4. to centrifugal electrospinning, [68] air-sealed centrifugal electrospinning, [69] near-field electrospinning (NFE), [70] coaxial electrospinning, [71] conjugate electrospinning, [72] bubble electrospinning, [73] multineedle electrospinning, [74] etc. (Figure 3).…”

Flexible strain sensors with high sensitivity and large working range prepared from biaxially stretched carbon nanotubes/polyolefin elastomer nanocomposites

“…To improve the properties of sensors, flexible sensors with diverse structures have been prepared by various processing methods; including electrospinning, vapor chemical deposition, casting, and 3D printing technology 10–12 . However, these methods are disadvantageous in terms of low efficiency, high cost, and difficult industrial production.…”

“…To improve the properties of sensors, flexible sensors with diverse structures have been prepared by various processing methods; including electrospinning, vapor chemical deposition, casting, and 3D printing technology. [10][11][12] However, these methods are disadvantageous in terms of low efficiency, high cost, and difficult industrial production. Biaxial stretching is a simple and effective film preparation technology, which is also a deformation form in some polymer processing approaches, such as thermoforming, film blowing, and extrusion.…”
