ANTIBACTERIAL PROPERTIES OF PAINT WITH THE ADDITION OF ZNO NANOPARTICLES

Abstract

The purpose of this study was to see how the antibacterial characteristics of ZnO nanoparticles were applied to wall paint to determine the effectiveness of ZnO nanoparticles in killing bacteria. Where ZnO is one of the metal oxides with good anti-bacterial properties through the formation of ROS. By modifying the percentage of ZnO nanoparticles used, namely 3%, 5%, 10%, and 15%, and 0% as a blank or comparison. Antibacterial properties were obtained through evaluation using the TPC method which stands for Total Plate Count. ZnO nanoparticles were obtained by synthesizing using the precipitation method. ZnO nanoparticles were characterized using XRD Instruments  to analyze the morphological structure
