| Résumé : |
o overcome the leaching problem associated with low-molecular-weight antimicrobial agents, a water soluble antimicrobial polymer, poly(N-acryloyl ciprofloxacin-co-acrylic acid), was designed and synthesized via acryloylation of the secondary amine in 7-piperazinyl substituent of ciprofloxacin and subsequent copolymerization with acrylic acid. The structure of the copolymer was characterized by 1H nuclear magnetic resonance (NMR), Fourier transform infrared (FTIR) spectra, X-ray photoelectron spectroscopy (XPS), and gel permeation chromatography (GPC). The copolymer was compatible with waterborne polyurethane for leather finishing, and remained antimicrobial even though the parent structure of ciprofloxacin molecule was altered. When incorporated into waterborne polyurethane leather coating as an antimicrobial agent, poly(N-acryloyl ciprofloxacin-co-acrylic acid) proved seldom leached out from the coating even after being rinsed for ten times. Based on these results, the water soluble antimicrobial copolymer designed in this study may prevent depletion of antimicrobial function of waterborne polyurethane leather coating, extending the lifetime of the leather products and enhancing their hygiene properties. |
