Title (EN) MICROFLUIDIC ASSISTED FABRICATION OF POLYMER MICROPARTICLE-METAL NANOPARTICLE COMPOSITES
(FR) FABRICATION ASSISTÉE PAR MICROFLUIDIQUE DE COMPOSITES MICROPARTICULES POLYMÈRES-NANOPARTICULES MÉTALLIQUES
Abstract:
(EN) The present application relates to polymer microparticle-metal nanoparticle composites, to methods of preparing polymer microparticle-metal nanoparticle composites and to uses of such composites. The methods comprise introducing into a microfluidic device, a composition comprising: a cationic metal nanoparticle precursor; a polymer microparticle precursor that comprises a plurality of photopolymerizable groups; and a photoreducer- photoinitiator; then irradiating the composition under conditions to simultaneously reduce the cationic metal and polymerize the photopolymerizable groups to obtain the composite.
(FR) La présente invention concerne des composites microparticules polymères-nanoparticules métalliques, des procédés de préparation de composites microparticules polymères-nanoparticules métalliques, et des utilisations de ces composites. Les procédés comprennent l'introduction, dans un dispositif microfluidique, d'une composition comprenant : un précurseur de nanoparticules d'un métal cationique ; un précurseur de microparticules polymères qui comprend une pluralité de groupes photopolymérisables ; et un photoréducteur-photoamorceur ; puis l'irradiation de la composition dans des conditions visant à simultanément réduire le métal cationique et polymériser les groupes photopolymérisables, pour obtenir le composite.
