4. ELECTROSPINNING

Electrospinning is as a versatile and cost-effective technique for producing multifunctional nanofibers from various polymers, polymer blends with diameters ranging from a few nanometers to several micrometers (usually between 50nm and 500nm). This non-mechanical, electrostatic technique involves the use of a high voltage electrostatic field to charge the surface of a polymer solution droplet and thus to induce the ejection of a liquid jet through a spinneret. In a typical process, an electrical potential is applied between a droplet of a polymer solution, a melt, held at the end of a capillary tube (or syringe needle) and a grounded target.

Electrospun nanofibers/nanowebs have several remarkable characteristics such as a very large surface-to-volume ratio, pore sizes within the nano range, unique physical and mechanical properties along with the design flexibility for chemical/physical functionalization.
