A novel, durable, long lasting, N-halamine siloxane monomer precursor, 5,5′-ethylenebis[5-methyl-3-(3-triethoxysilylpropyl)hydantoin] has been prepared and characterized by 1 H-NMR and FTIR for the purpose of functionalizing the surfaces of various materials. In this work, the precursor N-halamine moiety was attached by siloxane covalent bonding to surfaces of cotton fibers. Simulated laundering...
A series of copolymers incorporating N-halamine siloxane and quaternary ammonium salt siloxane units has been prepared. The primary function of the quat units was to render the siloxane copolymers soluble in water. The copolymers have been coated onto cotton swatches and evaluated for biocidal efficacy against Staphylococcus aureus and Escherichia coli O157:H7. It was determined that both N-halamine...
