| Outline of Final Research Achievements |
The nano-hybrid thin films of polymer and zirconia nanoparticles have been interested in their optical properties of high refractive index. In order to prepare their transparent thin films, the fine and stable zirconia nanoparticle dispersion is the most important substances, which is not re-aggregated in monomer solutions or polymer matrices. These nano-hybrid materials can be applied to opto-functional coatings for electronic devices such as displays, touch panels, etc. Zirconia nanoparticle dispersions in organic solvents could be prepared by using silane coupling agents as a dispersant, but it is difficult to obtain stable dispersions by a beads-mill process.
In this work, dual-site silane coupling agents or cyclic acid anhydrides as dispersants was applied for the preparation of zirconia nanoparticle dispersions. The hybrid materials of polymers or multi-functional acrylates with these zirconia nanoparticle dispersions were generated by the photo-curing under UV irradiation.
