  • Patent number: 8821907
    Abstract: 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.
    Type: Grant
    Filed: March 10, 2006
    Date of Patent: September 2, 2014
    Assignee: Auburn University Office of Technology Transfer
    Inventors: Shelby D. Worley, Jie Liang, Yongjun Chen, Royall M. Broughton, Jia-Wang Wang, Rong Wu, Unchin Cho, Jaewoong Lee, Kevin Barnes
  • Patent number: 7335373
    Abstract: N-halamine compounds which contain hindered amine and amide functional groups. Compounds include wherein X, X?, and X? independently are H, Cl, or Br, wherein no more than two of X, X?, and X? are H and wherein R, R?, and R? are independently alkyl groups containing 1 to 4 carbon atoms or hydrogen, and X and X? are independently H, Cl, or Br. Compositions comprising the compounds are also described. The compounds and/or compositions can be used, for example, for the purpose of constructing biocidal coatings and materials. The biocidal activity can inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as, virus particles.
