N-halamines As Novel Antimicrobial and Biofilm-controlling Additives for Polymers

摘要

A series of hydantoin-based N-halamines were synthesized. The antimicrobial activities of the samples were challenged with 108-9 CFU/mL of E. coli (gram-negative) and S. aureus (gram-pcsitive). All the samples provided a total kill of the bacteria tested. Shorter alkyl chain length resulted in faster antimicrobial actions. When CADMH were added into PS or HDPE as antimicrobial additives, they offered the polymeric materials with potent and durable antimicrobial functions.
