ELECTROHYDRODYNAMIC DEVICE AND METHOD FOR THE PRODUCTION OF NANOEMULSIONS AND NANOEMULSIONS THUS PRODUCED

摘要

The invention relates to an electrohydrodynamic method of generating double emulsions having a drop size in the micro or submicrometric range, of the water/oil/water (w/o/w) type, the oil/water/oil (o/w/o) type and oil/water (o/w)-type simple emulsions. The inventive method comprises the formation of an electrified compound jet in a bath of dielectric liquid [liquid(1)] having a diameter in the micrometric or submicrometric range, which is formed by a liquid (2) and a liquid (3) which flows inside the liquid jet (2) either in the form of drops or in the form of another inner jet. The inventive device and method can be used to obtain nanoemulsions and for encapsulation processes used in fields in which the generation and controlled manipulation of micro or nanometric drops and jets constitutes an essential part of the process.
