Acyclic N-Halamine Polymeric Biocidal Films.

摘要

10%, 20% and 40% concentrations of acyclic amide monomers, methacrylamide (MAM) and acrylamide (AM), were copolymerized with vinyl acetate (VAc). No significant differences between the synthesized copolymers and polyVAc were seen by proton nmr, FTIR and DSC analysis. Biocidal films formed by coating the copolymers onto polyester transparency slides and polyester fabric swatches were chlorinated by exposure to sodium hypochlorite solutions. Both S. aureus and E. coli O157:H7 were completely inactivated within 1 minute on the transparency slides and polyester fabric swatches derived from poly(VAc- co-MAM). The chlorine on the films was stable under UVA irradition and the surfaces were rechargeable upon chlorine loss.
