Hybrid films prepared from latex particles incorporating metal oxide nanoparticles

摘要

Metal oxide (ZrO_2) nanoparticle-dispersed polymer films (hybrid latex films) were prepared from polymer particles incorporating ZrO_2 nanoparticles (hybrid latex dispersion). The hybrid latex dispersions were synthesized by miniemulsion polymerization. The resulting films were transparent, and they derived their properties from the ZrO_2 nanoparticles. The refractive indexes of the films increased with the ZrO_2 content. Surface-modified ZrO_2 nanoparticles were dispersed successfully in a polymer matrix containing phosphoric acid groups, which interacts with the surfaces of the ZrO_2 nanoparticles and increases the compatibility between the polymer and ZrO_2.
