Abstract

In this study, colloidal Ag solution was spouted on the surface of the inorganic pigment using the hybridizer system and the spray nozzle. Then, the surface of the inorganic pigment was modified by titanium dioxide in order to possess antibacterial ability. Nano-sized colloidal Ag was made by using a seed sol method in this study. It was confirmed that the size of particle per unit weight becomes enlarged, as the addition of $AgNO_{3}$ increased, and as the time of reaction increased, in the manufacturing process of nano-sized colloidal Ag. The antibacterial measurement of the inorganic pigment showed that the growth of fungus was reduced as the reaction time increased. It was measured that the antibacterial activity was excellent at fixed time frame, after the antibacterial ability appeared in $5{\sim}7$ hours of the antibacterial inoculation experiment. The experiment of titanium dioxide's Photocatalyst effect showed $60{\sim}70%$ efficiency in about 80 minute reaction time of the dissolution results regarding measurements of benzene. It was shown that more than 90% of the dissolution efficiency was achieved in the reaction time of about 30 minute.
