An N-halamine acrylamide monomer was copolymerized with the sodium salt of 2-acrylamido-2-methylpropane sulfonic acid to produce water-dispersible/soluble polymers. The polymers were added into a water-based latex paint and the treated paints were rendered antimicrobial upon chlorination with dilute household bleach. The chlorinated paints were exposed to fluorescent and ultraviolet light for several periods of time. The bound chlorine on the polymers was remarkably stable and the remaining chlorine on the treated paints after several weeks of light exposure was sufficient to provide 6-log inactivations of both Gram-positive and Gram-negative bacteria within 5-10 min of contact time. The samples exposed light could be rechlorinated to their initial chlorine loadings, indicating that the polymers were also very stable toward light irradiation. This study describes an effective approach to prepare antimicrobial surfaces providing long-term disinfection.
