DISPERSION SOLUTION OF NANO-SIZED COMPOSITE MATERIALS WITH MULTIFUNCTIONALITY AND PREPARATION METHOD THEREOF

摘要

PURPOSE: Provided is a dispersion solution of nano-sized composite materials, silica bonded with silver particles dispersed in water or organic solvent by electrolysis. The dispersion solution has storage stability, sterilization, far infrared emission and deodorization. CONSTITUTION: The dispersion solution of nano-sized composite materials is prepared by the following steps of: preparing a colloidal silica solution containing 0.1-30wt.% of silica(3-50nm), alkaline solution of pH8-12; putting a negative electrode containing aluminum and a positive electrode containing silver(1-10nm) in the silica colloidal solution; and applying voltage to each electrode at 30-100deg.C.
