Electrospinning Technique

Electrospinning system uses an electrical charge to draw very fine (typically on the micro or nano scale) fibres from a liquid. When a sufficiently high voltage is applied to a liquid droplet, the body of the liquid becomes charged, and electrostatic repulsion counteracts the surface tension and a stream of liquid erupts from the surface, until it is finally deposited on the grounded collector.  

The properties of nanofibers:

• Huge surface area to volume ratio
• Low density
• Very high porosity 
• Improved physical and chemical properties

The advantages of Electrospinning technique :

• Continuous process
• Cost effective
• Controllable diameters from few nm to several microns

The electrospinning system mainly has vertical type and horizontal type according to the geometrical arrangements of ejecting capillary and collection target.
