Title:
METHOD FOR MANUFACTURING SPHERICAL MESOPOROUS SILICA CONTAINING DISPERSED SILVER NANOPARTICLES, AND SPHERICAL MESOPOROUS SILICA MANUFACTURED BY SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2011/129502
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing mesoporous silica containing dispersed silver nanoparticles, wherein the method is characterized in that spherical mesoporous silica containing dispersed silver nanoparticles is manufactured by adding a silver nitrate solution to an aqueous surfactant solution through a gel-sol process, and relates to spherical mesoporous silica manufactured by the method. Compared to the process that uses nanoparticles as a raw material, the method of the present invention uses a relatively cheaper silver nitirate solution and is thus more economical, and raises productivity to render mass production possible by applying this method on-site, thus making commercialization easy. Further, since silver nanoparticles are included in the mesoporous silica, there is no change in color and odor, and stability is achieved when silver nanoparticles are applied. Also, due to the silica, additional effects of far-infrared radiation and deodorization are achieved.
