摘要：
A new N halamine monomer, N-chloro-2,2,6,6 tetramethyl-4 piperidinyl methacrylate (CI-TMPM) was synthesized and used to prepare water based polymeric N-halamines by emulsion polymerization. The chemical structures of the samples were characterized with Fourier transform IR C-13 NMR UV/vis and differential scanning calorimetry analyses. Upon the addition of a small amount of the polymeric N halamine latex emulsions into commercial water based latex paints as antimicrobial additives, the new paints provided potent antimicrobial activities against staphylococcus aureus (S aureus. Gram positive bacteria), methicillin resistant S aureus (MRSA; drug-resistant Gram positive bacteria) vancomycin resistant enterococcus (VRE drug resistant Gram positive bacteria). escherichia coh (E coli Gram negative bacteria) Candida tropicahs (C tropicalis fungi) MS2 virus (15597 B virus), and Stachybotrys chartarum spore (S chartarum mold) and they successfully preveted biofilm formation and development. The antimicrobial functions of the new paints were long lasting for more than 1 year under normal in use conditions, easily monitorable by a simple potassium iodine/starch test and readily rechargeable if the functions were accidentally lost as a result of challenging conditions such as heavy soil flooding etc.
