Title (EN) METHOD FOR OBTAINING ENCAPSULATED NANOPARTICLES
(FR) MÉTHODE POUR L'OBTENTION DE NANOPARTICULES ENCAPSULÉES
Abstract:
(EN) The present invention relates to a method for obtaining at least one particle (1) comprising the following steps: (a) preparing a solution A comprising at least one precursor of at least one element selected from the group constituted by silicon, boron, phosphorus, germanium, arsenic, aluminium, iron, titanium, zirconium, nickel, zinc, calcium, sodium, barium, potassium, magnesium, lead, silver, vanadium, tellurium, manganese, iridium, scandium, niobium, tin, cerium, beryllium, tantalum, sulfur, selenium, nitrogen, fluorine, chlorine; (b) preparing an aqueous solution B; (c) forming droplets of solution A by a first means for forming droplets; (d) forming droplets of solution B by a second means for forming droplets; (e) mixing said droplets; (f) dispersing the mixed droplets in a gas flow; (g) heating said dispersed droplets at a temperature sufficient to obtain the at least one particle (1); (h) cooling of said at least one particle (1); and (i) separating and collecting said at least one particle (1); wherein the aqueous solution may be acidic, neutral, or basic; and wherein at least one colloidal suspension comprising a plurality of nanoparticles 3 is mixed with the solution A at step (a) and/or with the solution B at step (b). The present invention also relates to a device for implementing the method.
(FR) La présente invention concerne une méthode d'obtention d'au moins une particule (1) comprenant les étapes suivantes : (a) préparer une solution A comprenant au moins un précurseur d'au moins un élément choisi dans le groupe constitué par le silicium, le bore, le phosphore, le germanium, l'arsenic, l'aluminium, le fer, le titane, le zirconium, le nickel, le zinc, le calcium, le sodium, le baryum, le potassium, le magnésium, le plomb, l'argent, le vanadium, le tellure, le manganèse, l'iridium, le scandium, le niobium, l'étain, le cérium, le béryllium, le tantale, le soufre, le sélénium, l'azote, le fluor, le chlore ; (b) préparer une solution aqueuse B ; (c) former des gouttelettes de solution A par un premier moyen pour former des gouttelettes ; (d) former des gouttelettes de solution B par un second moyen pour former des gouttelettes ; (e) mélanger lesdites gouttelettes ; (f) disperser les gouttelettes mélangées dans un flux de gaz ; (g) chauffer lesdites gouttelettes dispersées à une température suffisante pour obtenir ladite/lesdites particule(s) ; (h) refroidir ladite/lesdites particule(s) (1) ; et (i) séparer et collecter ladite/lesdites particule(s) (1) ; la solution aqueuse pouvant être acide, neutre ou basique ; et au moins une suspension colloïdale comprenant une pluralité de nanoparticules 3 étant mélangée à la solution A à l'étape (a) et/ou à la solution B à l'étape (b). La présente invention concerne également un dispositif pour mettre en œuvre la méthode.
