摘要

process for the preparation of modified zno particles, modified zno particles, materials, dispersions or suspensions, process for the incorporation of modified zno particles in materials, and, use of modified zno particles. the invention relates to a method for producing modified zno particles in which a zinc salt and a base are mixed in a polar solvent and the polar solvent is optionally removed after precipitation of a precipitation product, resulting in a residue, being that the residue is absorbed in a non-polar solvent, surfactants are added, other active substances are optionally added, and then the modified zno particles are separated from other by-products. the invention also relates to a method for incorporating modified zno particles into materials, the modified zno particles being incorporated into the materials in the form of dispersions or suspensions, and the use of modified zno particles to protect materials against the effects light, heat, oxygen or radicals, as catalysts, for semiconductor layers or for cosmetic uses.
