HOLLOW SILICA PARTICLES, METHOD OF PREPARING THE SAME AND LOW-REFLECTION COATINGS USING THE SAME

摘要

PURPOSE: Hollow silica, a manufacturing method of the same, and a low reflective coating material manufactured using the same are provided to control the size of particles by synthesizing nanosilver crystals using polyol solvents with different viscosities. CONSTITUTION: A manufacturing method of hollow silica includes the following steps: nanosilver crystals are synthesized by using polyol solvents with adjusted viscosities; silica is coated on nanosilver crystals to synthesize silver-silica core-shell nanoparticles; and the silver cores of the silver-silica core-shell nanoparticles are etched. The polyol solvents are one or more selected from a group including ethylene glycol, 1,2-propanediol, 1,4-butanediol, or 1,5-pentanediol. The sizes of the nanosilver crystals are in a range between 30 and 50nm.
