/ MANUFACTURING METHOD OF MULTI-FUNCTIONAL FINE PARTICLES HAVING ULTRAVIOLET-PROOF AND ANTIBIOTIC FUNCTIONS AND THE MULTI-FUNCTIONAL FINE PARTICLES MANUFACTURED THEREFROM

摘要

Silica is added to the metal oxide nanoparticles to give a functional group. The silver compound is added again to give an antibacterial function by chelating, and then the organic UV-blocking agent is bonded again to give a UV-blocking function. The present invention relates to a method for producing an antibacterial / ultraviolet screening compound-functional fine particle which provides excellent functional and fine functional particles which are improved in light fastness to a dye and a multi-functional fine particle prepared from the method.;
