Abstract
ABSTRACT In this study, we synthesized a new organic-inorganic hybrid material based on N-halamine and TiO2 using miniemulsion polymerization. N-halamine as a broad-spectrum antimicrobial agent has a more powerful inactivation ability over other agents. The novel TiO2 based nanocomposites (MPS-TiO2@PVBC-DMH-Cl NPs) demonstrated significantly enhanced UV stability, potent antibacterial and antifungal activities. Upon addition of a certain amount of the nanoparticles into commercial water-based latex paints as UV-stable antibacterial additives, the prepared paint successfully prevented biofilm formation against model microbe cells. The prepared paint was also stable under UV exposure, and readily rechargeable if efficacies were lost under challenging conditions.
