Antimicrobial polymers containing melamine derivatives. II. Biocidal polymers derived from 2‐vinyl‐4,6‐diamino‐1,3,5‐triazine

Abstract

Poly(2‐vinyl‐4,6‐diamino‐1,3,5‐triazine) (PVDAT) and a series of poly(styrene‐co‐2‐vinyl‐4,6‐diamino‐1,3,5‐triazine) (PS‐co‐VDAT) copolymers were synthesized via conventional free‐radical polymerizations. The polymer structures were confirmed by Fourier transform infrared, NMR, and elemental analysis. The molecular weights were determined by gel permeation chromatography studies, and the thermal properties were characterized by differential scanning calorimetry and thermogravimetric analysis. After treatment with chlorine bleach, PVDAT and PS‐co‐VDAT provided potent antimicrobial functions against multidrug‐resistant Gram‐negative and Gram‐positive bacteria. The antimicrobial functions were durable for longer than 3 months and rechargeable for more than 50 times. The structure–property relationship of the polymers was further discussed. © 2005 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 43: 4089–4098, 2005

Biocidal efficacy, biofilm-controlling function, and controlled release effect of chloromelamine-based bioresponsive fibrous materials

“…One of the research interests of this group is the development of N-halamine-based polymeric materials to achieve biocidal and biofilms-controlling functions [34,[39][40][41]. Our most recent efforts have been focused on a class of unique N-halamines, chloromelamines, which have already been safely used as water and food disinfectants [42].…”

N‐halamine‐based chitosan: Preparation, characterization, and antimicrobial function

“…This process consumes chlorines, but the consumed chlorines can be readily recharged by another halogenation treatment 16–18. Thanks to these attractive properties, N ‐halamine structures have been incorporated into different materials to provide potent, durable, and rechargeable biocidal functions against a broad spectrum of microorganisms 17, 19–31…”

N‐bromo‐hydantoin grafted polystyrene beads: Synthesis and nano‐micro beads characteristics for achieving controlled release of active oxidative bromine and extended microbial inactivation efficiency

“…A ratio to reactive sites of 2.5:1 and 1.5:1 was used, and reagent amounts/volumes were accordingly adjusted. Before and during bromination, beads samples were taken after every 1,8,24, and 72 h. These samples were filtrated and washed with 1 L DDW in 100 mL portion and then dried. Beads were analyzed for Br% by elemental analysis and the iodometric/thiosulfate titration method.…”
