Patent ID: 8486428

Claim:
A rechargeable aliphatic N-halamine polymer comprising: a cotton substrate; a rechargeable aliphatic N-halamine polymer grafted directly to the cotton substrate, wherein the rechargeable aliphatic N-halamine polymer is formed from the polymerization of one or more aliphatic N-halamine methacrylamide monomers selected from N-alkyl-monosubstituted, N-alkylamino-monosubstituted, and N,N-dialkyl-substituted, N,N-dialkylamino-disubstituted; and one or more halides associated with the one or more aliphatic N-halamine methacrylamide monomers, whereby the one or more halides provide inactivation of bacteria cells, spores, fungus, yeasts, viruses or a combination thereof.
