Title
(EN) SYSTEM FOR FORMING JANUS PARTICLES
(FR) SYSTÈME DE FORMATION DE PARTICULES JANUS
Abstract
(EN) The invention is a method of forming Janus particles, that includes forming an emulsion that contains initial particles, a first liquid, and a second liquid; solidifying the first liquid to form a solid that contains at least a portion of the initial particles on a surface of the solid; and treating the exposed particle sides with a first surface modifying agent, to form the Janus particles. Each of the initial particles on the surface has an exposed particle side and a blocked particle side.
(FR) L'invention concerne un procédé de formation de particules Janus. Le procédé comprend les étapes consistant à former une émulsion qui contient des particules initiales, un premier liquide et un second liquide; solidifier le premier liquide pour former un solide qui contient au moins une partie des particules initiales sur une surface du solide; et traiter les côtés exposés des particules avec un premier agent modificateur de surface pour former les particules Janus. Chacune des particules initiales sur la surface comprend un côté exposé de particule et un côté bloqué de particule.
