Abstract
A nanoparticle-resin composite material is provided. The material has a transparent characteristic and a refractive index of at least 1.55 in the visible light region. The composite material includes inorganic nanoparticles dispersed in a polymer having a siloxane bond, the inorganic nanoparticles being coated with an organic compound. The organic compound is at least one compound selected from the group consisting of carboxylic acids, phosphinic acid, phosphonic acid, sulfinic acid, sulfonic acid, and thiols, and the selected compound contains an aryl group or an aryloxy group. The polymer is selected from the group consisting of methylphenyl polysiloxane, methylphenyl hydrogen polysiloxane, a mixture methylphenyl polysiloxane and methylphenyl hydrogen polysiloxane, or methylphenyl polysiloxane, methylphenyl hydrogen polysiloxane, and a mixture of methylphenyl polysiloxane and methylphenyl hydrogen polysiloxane. Parts of the side chains and/or terminals of the methylphenyl polysiloxane and the methylphenyl hydrogen polysiloxane are substituted by epoxy groups, carboxyl groups, carbinol groups, methacryl groups, polyether groups, or vinyl groups.
