Nanomaterials can be used as antimicrobial additives in different applications such as water-borne paints. The fabrication of antimicrobial paints is important because of the prevention of indoor biological colonization, paint bio-deterioration, and health problems in people and pets. The antipathogen paints have several applications in different areas such as health centers, elderly care centers, emergency rooms, and hospitals. In this work, Ag/RGO nanocomposite was synthesized as an antimicrobial waterborne paint additive. The antibacterial activity of a waterborne paint formulated with Ag/RGO nanocomposite was evaluated against Escherichia coli (ATCC25922) as a gram-negative bacterium using the microdilution method. The antibacterial tests showed that Ag/RGO nanocomposite has strong antibacterial activity.
