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
