A simple method for the preparation of thin, zinc oxide nanoparticle-containing films showing high UV absorption, high transmittance in the visible range (>88%), and water repellence with contact angles of 120° is presented. The films are coated from an emulsion containing the hydrophobic polymer and the nanoparticles. This emulsion was prepared by mixing commercial o/w emulsions used for hydrophobic coatings on textiles with ZnO nanoparticle-containing o/w emulsions. The latter were designed so that the mixed coating formulation could be prepared without breaking. Preparation and properties of the o/w emulsions as well as the final films are elaborated. The performance of hydrophobic and hydrophilic ZnO nanoparticles during preparation and in the final film is evaluated.
