Title:
METHOD FOR SYNTHESIZING CORE MATERIAL USED FOR SYNTHESIZING HOLLOW NANO-SILICA MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/137134
Kind Code:
A1
Abstract:
The present invention relates to a method for synthesizing core material nanoparticles used for synthesizing hollow nano-silica particles, and the method for synthesizing a nano-core material, comprises the steps of: (a) adding polyvinylpyrrolidone as a stabilizer to a distilled water solvent; (b) adding AIBA(2,2;-azobis dihydrochloride as an initiator; (c) adding styrene as a precursor; and (d) mixing the solution to which the stabilizer, the initiator, and the precursor are added for 24 hours at a temperature between 60 degrees to 80 degrees, wherein the particle size is adjusted by controlling the concentration of at least one of the solvent, the stabilizer, and the initiator. The present invention enables easy synthesis of core material nanoparticles having various sizes by using various synthesis techniques, and provides the method for synthesizing small core material nanoparticles by improving the steps to be simpler and more efficient.
