N-halamine / quaternary ammoniumpolysiloxane

Abstract

Precursor N-halamine / quaternary ammonium random copolymers which are soluble in water for the purpose of functionalizing sutfaces or materials so as to render them biocidal upon exposure to oxidative halogen solutions. The biocidal function can be Simpatted to the precursor N-halamine moiety either before or after siloxane bonding or adhesion to the surface or material The biocidal surfaces and materials can then be used to inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as virus particles, that can cause infectious diseases and those microorganisms that cause noxious odors and unpleasant coloring such as mildew Examples of surfaces and materials which can be rendered biocidal include, but are not limited to, cellulose, chitin, chitosan, synthetic fibers, glass, ceramics, plastics, rubber, cement grout, latex caulk, porcelain, acrylic films, vinyl, polyurethanes, silicon tubing, marble, metals, metal oxides, and silica.
