Title:
METHOD FOR MANUFACTURING SILICA NANOPARTICLES WITH EXCELLENT WATER DISPERSION PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2014/119913
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing water-dispersible silica nanoparticles. More specifically, the present invention relates to a method for manufacturing silica nanoparticles, which includes a step of carrying out a reaction by adding an alkaline substance and a silica precursor to a solution obtained by dissolving polyvinyl pyrrolidone in a mixed solution of C1-C4 alcohol and water.
