Title (EN) METHODS FOR PRODUCING MULTIFACETED NANOPARTICLES USING POLYMER BRUSH ARCHITECTURES
(FR) PROCÉDÉS DE PRODUCTION DE NANOPARTICULES À PLUSIEURS FACETTES À L'AIDE D'ARCHITECTURES DE BROSSE POLYMÈRE
Abstract:
(EN) Methods for producing multifaceted nanoparticles and uses thereof are disclosed. One method for producing multifaceted nanoparticles can include obtaining a template that includes a substrate and a polymer brush having a plurality of polymers each attached by a first end to the substrate and each having a free opposing second end located opposite the first end; contacting the polymer brush with a solution that includes a nanoparticle precursor material; and forming, from the precursor material and the functional groups located on the second end of the plurality of polymers, multifaceted nanoparticles. The second ends of the polymer chains are functionalized with functional groups that have an affinity for the facets of the multifaceted nanoparticles.
(FR) L'invention concerne des procédés de production de nanoparticules à plusieurs facettes et leurs utilisations. Un procédé de production de nanoparticules à plusieurs facettes peut comprendre l'obtention d'un modèle qui comprend un substrat et une brosse polymère comportant une pluralité de polymères fixés chacun par une première extrémité au substrat et comportant chacun une seconde extrémité opposée libre située à l'opposé de la première extrémité ; la mise en contact de la brosse polymère avec une solution qui comprend un matériau précurseur de nanoparticule ; et la formation, à partir du matériau précurseur et des groupes fonctionnels situés sur la seconde extrémité de la pluralité de polymères, des nanoparticules à plusieurs facettes. Les secondes extrémités des chaînes polymères sont fonctionnalisées avec des groupes fonctionnels qui ont une affinité pour les facettes des nanoparticules à plusieurs facettes.
