| Outline of Final Research Achievements |
In this work, we aimed to prepare the polymer composite exhibiting high reflactive index. Our approach is emphasized by no use of any surfactant to disperse an inorganic component in polymer. For this purpose, direct polymerization of acrylate or metacrylate monomer with metal oxide nano-particles, and also a casting method of a polymer solution composed of hydrophilic polymer with metal oxide nano-particles were investigated. The successful results were obtained by selecting monomers or polymers having hydroxy and ester or amide bonds as an organic omponent and hetropoly acid or rod-like titania nano-particles. The most impactful result was shown in the combination of poly(hydroxyethyl acrylamide) with rod-like nano-titania. The highest reflactive index reached n = 1.9.
