Biocidal N-halamine epoxides

摘要

N-halaminehydantoinyl epoxide compounds which can be used for the construction of coatings and materials which can be rendered biocidal by exposure to halogen solutions either before or after curing the coating or material are disclosed. The biocidal coatings and materials can then be used to inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as virus particles, which can cause infectious diseases, and those microorganisms which cause noxious odors and unpleasant coloring such as mildew. The coatings are compatible with a variety of substrates including, but not limited to, cellulose, chitin, chitosan, synthetic fibers, cement grout, latex caulk, acrylic films, polyurethanes, plastics and paints.

主权项

1. A method for rendering a material biocidal, the method comprising:
a) adding an N-halamine or a precursor of N-halamine comprising a hydantoinyl portion and an epoxide portion to the material, wherein the N-halamine or the precursor of N-halamine is a hydantoinyl epoxide having a structure: and wherein R1 and R2 are one or more of C1-C8 alkyl groups, methyl groups, cycloalkyl groups and phenyl groups and X is one of H, Cl, and Br; and b) curing the N-halamine or the precursor of N-halamine with the material, such that the epoxide portion opens and attaches the hydantoinyl portion to a portion of the material.
