Modified ZnO nanoparticles

A method for producing a modified zinc oxide nanoparticles, with the proviso that the reaction is carried out in a water content less than 5% by weight, based on the total amount of solvent and water, zinc oxide nanoparticles dissolved in a solvent the tetraalkyl in the presence of ammonia or an amine - orthosilicate and optionally, wherein the reaction with the organosilane, the method for producing the modified ZnO nanoparticles. The preparation obtained by the method, Si-O-having an alkyl group and modified zinc oxide nanoparticles are soluble in organic solvents. Liquid or solid formulations containing modified ZnO nanoparticles. Containing modified ZnO nanoparticles, organic materials of inanimate, such as plastic or paint. The method for stabilizing against the organic material of inanimate light, the action of radical or heat, time, This material, optionally containing UV absorbers and / or stabilizers as further additives modified ZnO nanoparticles are added.
