Abstract:
(EN) A zinc oxide polymer nanocomposite composed of zinc oxide nanoparticles. The zinc oxide nanoparticles of the nanocomposite have an average particle size of about 1 nanometer to about 20 nanometers. Suitable polymers of the nanocomposites have less than about 500 ppm alkali metal. A process is provided for preparing the zinc oxide polymer nanocomposites comprising a) preparing a first combination comprising zinc oxide nanoparticles and a polymer; b) preparing a second combination comprising the first combination and an organic solvent; and c) precipitating the zinc oxide nanoparticles and the polymer out of the second combination. The zinc oxide nanoparticles of the first combination have an average particle size of between about 1 nanometer and about 20 nanometers.
(FR) La présente invention concerne un nanocomposite polymère d'oxyde de zinc composé de nanoparticules d'oxyde de zinc. Les nanoparticules d'oxyde de zinc du nanocomposite présentent une taille moyenne des particules comprise entre environ 1 et environ 20 nanomètres. Des polymères appropriés des nanocomposites comportent moins d'environ 500 ppm de métal alcalin. Cette invention concerne également un procédé de préparation des nanocomposites polymères d'oxyde de zinc consistant: a) à préparer une première combinaison comprenant des nanoparticules d'oxyde de zinc et un polymère; b) à préparer une deuxième combinaison comprenant la première combinaison et un solvant organique; et c) à précipiter les nanoparticules d'oxyde de zinc et le polymère hors de la deuxième combinaison. Les nanoparticules d'oxyde de zinc de la première combinaison présentent une taille moyenne des particules comprise entre environ 1 et environ 20 nanomètres.
