Abstract
Process for the preparation of modified ZnO particles in which a zinc salt and a base are mixed in a polar solvent and, if appropriate after the precipitation of a precipitation product, the polar solvent is removed and a residue is obtained, where the residue is taken up in a nonpolar solvent, surface-active substances are added, optionally further effect substances are added and then the modified ZnO particles are separated off from further by-products. Materials such as plastics, coatings or paints comprising modified ZnO particles. Methods for the incorporation of modified ZnO particles into materials, where the modified ZnO particles are incorporated into the materials in the form of dispersions or suspensions. Use of modified ZnO particles for protecting material against the effect of light, heat, oxygen or free radicals, as catalysts, for semiconductive films or cosmetic applications.
