Abstract
N-halamine biocidal materials and coatings are provided. Monomeric oxazolidinones or hydantoins are homopolymerized or copolymerized with other monomers so as to produce materials or coatings, which upon exposure to solutions of chlorine or bromine become biocidal. The biocidal materials and coatings are effective at inactivating microorganisms upon surface contact and are regenerable following loss of efficacy upon further exposure to solutions of chlorine or bromine. Surfaces which could be treated with the materials and coatings include, but are not limited to: glass, plastic, metals, fibers, and wood for use in pool and tank liners, food wrappers, catheters, paints, tiles, shower walls, fabrics, sterile bandages, pipes, medical and dental coatings, preservatives, and the like.
