AGGREGATE OF SPHERICAL CORE-SHELL CERIUM OXIDE/POLYMER HYBRID NANOPARTICLES AND METHOD FOR PRODUCING THE SAME

摘要

Provided are an aggregate of spherical core-shell cerium oxide/polymer hybrid nanoparticles, a method for producing the same, and a product, such as an ink or an anti-reflection film containing a high refractive index layer. The aggregate of spherical core-shell cerium oxide/polymer hybrid nanoparticles wherein the cerium oxide serves as the core and the polymer serves as the shell comprises: a high concentration of core-shell cerium oxide/polymer hybrid nanoparticles at a volume ratio of 32% or greater; and a fixing agent which is filled between the core-shell cerium oxide/polymer hybrid nanoparticles. The aggregate consists of spherical secondary particles obtained by the uniform distribution of the core-shell cerium oxide/polymer hybrid nanoparticles, and is synthesized using the polyol method. The aggregate has excellent mechanical strength, light transmittance, and UV-ray shielding properties.
