The present invention provides a method for producing a dispersion of metal oxide nanoparticles, comprising the steps of: a) preparing metal oxide nanoparticles having a size of 5 nm to 500 nm; b) adding a solvent and a surface treatment agent to the metal oxide nanoparticles, C) adding a solvent to the polymer resin material, and then preparing a polymer matrix solution by a mixing process; and d) adding the polymer matrix solution to the metal oxide nano solution, Characterized in that the metal oxide nanoparticle dispersion of the metal oxide nanoparticle dispersion is guided in a collective form and the aggregate size is controlled within a range of 10 nm to 5 μm, Oxide nanoparticle dispersion. |
