Abstract

Organic-inorganic hybrid materials by dispersing inorganic nanoparticles in organic polymers are expected as functional substances with synergistic properties. Recently, high refractive index thin films are most important materials for optical devices such as flat panel display, touch panel, etc. These hybrids with dispersion of surface-modified zirconia nanoparticles can provide the controlled refractive index materials. It is necessary for the preparation of transparent hybrid materials to disperse zirconia nanoparticles in organic solvent or polymer solution by a beads mill process. Effective surface modifications of zirconia nanoparticles were successfully developed by two treatments of (1) with silane coupling agent and isocyanate compound and (2) with dual-site silane coupling agent. These dispersions can be applied to prepare the high refractive index thin films.
