52 Electrospraying
Electrospraying, also known as electrodynamic spraying, is a process of producing diminutive droplets with submicron sizes by means of an electric field.
The phenomenon of the interaction of a liquid with an electric field was first reported by William Gilbert in the late 16th century, who discovered that a water droplet transformed into a conical shape when a piece of charged amber was held close to it. The principles by which an electric field can deform the interface of a liquid droplet was established by Lord Rayleigh in 1882 and further developed by Zeleny in 1917 and Sir Taylor in 1964. The theory of charged droplets states that if an electrified field is applied to any droplet, the electric ...
