Electrospinning is the method of using a high voltage power supply to produce ultra small diameter fibers. Electrospinning process can be used to produce nanofibers from many synthetic and natural polymers. Some of the attractive properties of the electrospun nanofibers are the small diameter, high porosity and high surface-to-volume ratio. The polymer that you want to make nanofibers are mixed with a solvent and the solution is loaded inside the syringe. Syringe pump flow rate is adjusted to desired flow rate and high voltage is applied to the liquid solution to create a charged jet of polymer solution. When this jet travels in air, the solvent evaporates and leaves behind a charged fiber. Because of the intense electric field that exists between the needle tip and rotating collector, the fibers are electrostatically elongated and collected on the metal sheet. The apparatus used in the electrospinning process is shown in this video. https://sprucescience.com/products/ta... #electrospinning #science #youtube #nanotechnology #highvoltagepowersupply #polymer
