elektrospinding
Electrospinning is a fabrication method for producing ultrafine fibers from polymer solutions or melts by applying a high electric field. A viscous polymer solution is loaded into a syringe and extruded through a spinneret. Under a strong electric potential, charges accumulate at the liquid surface, creating a Taylor cone. When the electrostatic forces exceed surface tension, a jet is ejected, is stretched and thinned as the solvent evaporates, and solid fibers are deposited on a grounded collector.
Typical equipment includes a syringe pump, a conductive needle or spinneret, a high-voltage power supply, and
Applications are wide and include filtration membranes with high surface area, tissue engineering scaffolds, wound dressings,
Limitations include relatively low production rates for laboratory-scale setups and solvent handling concerns; scaling up requires
