Abstract

L'invention concerne un procédé permettant de générer, de façon électrohydrodynamique, des émulsions doubles, ayant la taille de gouttes micrométriques ou submicrométriques, des types eau-huile-eau (w/o/w) et huile-eau-huile (o/w/o) et des émulsions simples du type huile-eau (o/w). Le procédé consiste à former, dans un bain de liquide diélectrique [liquide(1)] un jet électrifié composé, de diamètre à l'échelle micrométrique ou submicrométrique, formé par un liquide (2) et un liquide (3) qui s'écoule à l'intérieur du jet de liquide (2), soit sous forme de gouttes, soit sous forme d'un autre jet intérieur. Le dispositif et le procédé selon l'invention peuvent servir à obtenir des nanoémulsions et des processus d'encapsulation qui trouvent leurs applications dans des domaines où la génération et la manipulation contrôlée de jets et de gouttes de taille micrométrique ou nanométrique constitue une partie essentielle du processus.
