The present invention relates to a method for preparing a high refractive index organic-inorganic composite having enhanced dispersibility and, more specifically, to a method for preparing a high refractive index organic-inorganic composite having enhanced dispersibility by forming a high refractive index organic-inorganic composite with a benzoate compound and a high refractive index nano-sized inorganic oxide, which is synthesized by a sol-gel method, using a gas-phase method or a liquid-phase method and then chemically bonding the surface of the organic-inorganic composite with a UV-curable resin monomer. Previously, the process was complicated since the surface was modified with a hydrophobic coupling agent and then dispersed the same onto a resin. However, by the method for preparing a high refractive index organic-inorganic composite having enhanced dispersibility according to the present invention, the process becomes simplified since a dispersion step after surface modification is omitted by bonding the UV-curable resin monomer to the high refractive index organic-inorganic composite, and thus the surface of particles are given hydrophobicity and the dispersibility of the composite can be enhanced. In addition, the high refractive index organic-inorganic composite having enhanced dispersibility prepared by the method can keep the shape self-reliantly without using a stiffening member such as a basic material and the like, extends the degree of freedom of the design of a final product, reduces the number of LED light sources so as to reduce electric power consumption and save costs, thereby effectively saving energy in an aspect of energy efficiency. |
