Electrospinning is an established method of producing nano- and micro-fibers from a wide variety of natural and synthetic polymers is knows as  Electrospinning

The method used to produce these fibers is as follows:

Introducing a  polymer solution at a constant flow rate through a small restriction such as a syringe needle.

A high voltage, typically 10 to 30 kV, is connected to the needle; it is the applied voltage that induces a charge on the surface of the liquid droplet; when a critical charge is reached, the physical shape of the droplet surface changes, the hemispherical surface of the fluid elongates and a Taylor cone forms.
