  What is the Electrospinning instrument?

Electrospinning in an industrial process in which a high voltageelectrical charge is used to create polymer filament fibers.

 What is the required equipment?  High Voltage (5-100kW) Power Supply

Micro-pump which it can give precise flow (0.1-100 ml/h)

Insulation Materials

Collector Plate

Needle

Ventilation Fans

Light and other enhancements

 What is the Electrospinning method?

Electrospinning method is extracted by fibers with help of electrostatic forces.Firstly, polymer solution is prepared. The solution is filled into syringe. Afterinsert the needle of syringe then that is placed in pump of syringe. The pump ofsyringe’s flow rote is set. One of crocodile which connect the voltage is attached end of the needle, theother one is attached the plate. When the voltage is turned on, the solution andthe collection plate loaded up. The solution begins to flow. When the voltageraises, electrostatic forces effect on drop of the solution. 

Whereas, this electrostatic forces approach a size of defeat surfacetension, the charged polymer solution starts to move towards the plate.The solution evaporates with the effect of electrostatic forces. Thepolymer achieves nano-size and stretch such as wire. Nanofibers shapedlike crotch is obtained on the plate. This operation is performed at highvoltage (5-30 kW). Fibers which are produced with this method havegenerally diameter between 40 to 2000 nanometers.

 What are the parameters used and noticed?Most of parameters may affect the result of this method. Mainly parameters are thedistance between flow rate, voltage power, and needle tip.The overall aim of all these adjustments is to optimize the diameter of the fiber and toprovide permanent production.If the required parameters don't achieve, beaded structures occur.

 What are application area of materialswhich product with method of

electrospinning?
