The process of electrospinning is low-cost procedure that creates nanofibres through an electrically charged jet of polymer solution or polymer melt. In the process of electrospinning the nanofibres are created through an electrically charged jet of polymer solution or polymer melt. Electrospinning process consists schematically of a pipette holding the polymer solution, two electrodes, a DC voltage supply in the kV range (tens of kV), and a grounded collector. The high voltage causes drawing of the polymer drop from the tip of the pipette into a fibre. The electrically charged jets are collected as a web of fibres on the surface of a grounded collector. During their passage from the pipette to the collector a solvent is evaporated, and hence a diameter of the fibres gets thinner. |
