GOLD NANOFLUID, SILVER NANOFLUID, AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a method of manufacturing gold nanoparticles and silver nanoparticles capable of reducing a manufacturing time. The gold nanofluid manufacturing method adds ultrasonic energy to an ultrasonic water tank, mixes the ultrasonic energy with water after mixing chloroauric acid (HAuCl_4) and sodium citrate powder in a container, and the container placed into the ultrasonic water tank in which a water temperature maintains at 70-90°C. The silver nanofluid manufacturing method comprises: a step of placing silver nitrate (AgNO_3) and propylene glycol fluid in a container, and adding polyvinylpyrrolidone (PVP); a step of placing the container in an ultrasonic water tank maintaining 20-30°C, and adding ultrasonic energy to the ultrasonic water tank; a step of placing sodium borohydride (NaBH_4) into the mixed liquid in the container after the above two steps; and a step of mixing the container while adding ultrasonic energy to the ultrasonic water tank after the third step.;COPYRIGHT KIPO 2016
