Abstract

An antimicrobial paint is disclosed. The antimicrobial paint comprises a carrier fluid, a binder, a sulfonated polymer and optionally at least an additive. The sulfonated polymer is selected from the group of perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones such as polyether sulfone, sulfonated polyketones such as polyether ketone, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer is sufficiently or selectively sulfonated to contain from 10-100 mol % sulfonic acid or sulfonate salt functional groups based on the number of monomer units, for killing at least 99% of microbes in less than 30 minutes, or in less than 5 minutes of coming into contact with a substrate coated in the antimicrobial paint composition.
