EFFECT OF CALCINATION TEMPERATURE ON ANTIMICROBIAL PROPERTIES OF ZnO/Ag NANOCOMPOSITE INCORPORATED IN ARCHITECTURAL PAINTS

In this work, ZnO/Ag nanocomposite were successfully synthesized using sol-gel process in different calcinations temperature and characterized by X-ray diffraction and scanning electron microscopy. These nanocomposites can be applied as the effective antibacterial or antifungal additives for architectural paints. The antibacterial activity was evaluated by inhibition zone test for Escherichia coli. Based on the presented results it can be stated that these materials are very effective biocides and The small crystal size and large surface area of the hetero structure nanoparticles contribute to antibacterial enhancement.
