Thermo-optic Coefficients of Hybrid Polymer with Metal Oxide Nanoparticles

摘要

To control thermo-optic (T-O) coefficient of polymer materials, hybrid polymer system with inorganic nanoparticles was examined. Polymer materials have high T-O coefficient but low refractive index. On the other hand, inorganic materials have low T-O coefficient but high refractive index. Then surface treated inorganic nanoparticles were dispersed into epoxy polymers. By increasing inorganic nanoparticle contents, refractive index of hybrid polymer changed and its T-O coefficient decreased.
