Title
(EN) STABLE DISPERSIONS OF MONOCRYSTALLINE NANOMETRIC SILVER PARTICLES
(FR) DISPERSION STABLES DE NANOPARTICULES MONOCRISTALLINES D'ARGENT
Abstract
(EN)
A concentrated dispersion of nanometric silver particles, and a method of producing the dispersion, the dispersion including a first solvent; a plurality of nanometric silver particles, in which a majority are single-crystal silver particles, the plurality of nanometric silver particles having an average secondary particle size (d50) within a range of 30 to 300 nanometers, the particles disposed within the solvent; and at least one dispersant; wherein a concentration of the silver particles within the dispersion is within a range of 30% to 75%, by weight, and wherein a concentration of the dispersant is within a range of 0.2% to 30% of the concentration of the silver particles, by weight.
(FR)
La présente invention concerne une dispersion concentrée de nanoparticules d'argent, et un procédé de production de la dispersion, la dispersion comprenant un premier solvant; une pluralité de nanoparticules d'argent, une majorité de celles-ci étant des particules d'argent monocristallines, la pluralité de particules d'argent nanométriques ayant une taille moyenne des particules secondaires (d50) dans une plage allant de 30 à 300 nanomètres, les particules étant dispersées dans le solvant; et au moins un dispersant; une concentration des particules d'argent dans la dispersion étant située dans une plage allant de 30 % à 75 %, en poids, et une concentration du dispersant étant située dans une plage allant de 0,2 % à 30 % de la concentration des particules d'argent, en poids.
