摘要： La présente invention a pour objet un procédé de préparation de particules comprenant au moins un ion métallique, comprenant les étapes suivantes :a) on met en solution ou dispersion aqueuse au moins un précurseur comprenant un cation métallique ; b) on effectue éventuellement une hydrolyse partielle dudit précurseur, c) on met en contact le précurseur issu de l'étape a) ou le précurseur partiellement hydrolysé issu de l'étape b), avec au moins un copolymère peigne hydrosoluble comportant soit un squelette anionique complexant et des chaînes latérales hydrophiles stabilisantes, soit un squelette neutre stabilisant et des chaînes latérales hydrophiles anioniques complexantes, soit au moins l'un des deux copolymères précités, associé à au moins un polymère hydrophile anionique complexant ; d) On effectue une hydrolyse partielle ou totale du produit obtenu lors de l'étape c). Elle a de même pour objet les particules susceptibles d'être préparées selon le procédé de l'invention, lesdites particules présentant une taille moyenne comprise entre 2 et 500 nm et de préférence entre 2 et 300 nm. Elle concerne enfin l'utilisation de telles particules dans le polissage mécanique d'objets durs, dans l'élaboration de pigments, de céramiques mixtes pour l'électronique, dans le renforcement de matrices polymériques, dans les dispersions fongicides ou biocides, dans le captage de dérivés soufrés, dans le captage des mauvaises odeurs.

摘要： The invention concerns a method for preparing particles comprising at least a metal ion, including the following steps: a) preparing a solution or an aqueous dispersion of at least a precursor containing a metal cation; b) optionally partly hydrolyzing of said precursor; c) contacting the precursor derived from step a) or the partly hydrolyzed precursor derived from step b), with at least a water-soluble comb polymer comprising either a complexing anionic skeleton and stabilising hydrophilic side-chains, or at least a stabilising neutral skeleton and complexing anionic hydrophilic side-chains, or at least one of two said polymers, associated with at least a complexing anionic hydrophilic polymer; d) partly or completely hydrolyzing the product obtained at step c). The invention also concerns particles obtainable by said inventive method, said particles having an average size ranging between 2 and 500 nm and preferably between 2 and 300 nm. The invention further concerns the use of such particles for mechanical polishing of hard objects, in preparing pigments, mixed ceramics for electronics, for reinforcing polymeric matrices, in fungicidal or biocidal dispersions, for capturing sulphured derivatives, for capturing bad odours.

摘要： The invention concerns a method for preparing mineral colloidal particles in aqueous dispersion with controlled size from a precursor, comprising a) aqueous solution heat treatment of said precursor which is a metal cation mineral salt; b) complexing of the product resulting from a) with at least a water soluble block copolymer comprising a complexing anionic hydrophilic block and at least a stabilising non-ionic hydrophilic block; and c) partial or total hydrolysis of said precursor to obtain a controlled growth of mineral particles in the form of an aqueous dispersion. The invention also concerns the use of said particles as reinforcing fillers for polymers.
