What is electrospinning?

Electrospinning is a technique to stretch a liquid into the form of a yarn and is being looked upon as a surgeon’s new tool for sutures without scars. In this technique, an electrically charged polymer solution is fed through a small opening or needle and, because of its charge, the solution is sucked towards a grounded collecting plate. As the jet of polymer flashes, the solvent gradually evaporates and a charged polymer fibre is left. The charge dissipates and a non-woven mat with tiny fibres is left. The fibres are between 50 nanometres and 10 microns in diameter.
