Continuous Dual-Track Fabrication of Polymer Micro-/Nanofibers Based on Direct Drawing

“…The most popular nanofiber fabrication method is electrospinning, which is joined by several other manufacturing techniques such as blow/jet spinning, − centrifugal spinning, − hand spinning (Figure A,B), , forcespinning, , microfluidic spinning, magnetospinning, , melting spinning, pull spinning, rotary jet spinning, − touch spinning, spinneret-based tunable engineered parameters technique (STEP), , and spun-wrapped aligned nanofiber (SWAN), or any combination of these techniques. − Despite the versatility and popularity of electrospinning, the technique remains limited in both throughput and the range of materials used. Most notably, electrospinning has been highly limited for making nanofibers comprised of polymers that have poor solubility in solvents or high electrical resistivity, such as polyolefins (e.g., polyethylene and polypropylene). , Furthermore, high-voltage electrical fields and sensitivity to solution conductivity and environmental conditions challenge existing systems.…”
