Popis: | A viable method for coating of cellulose fiber with quaternarized N-halamine is reported in this article. The use of quaternary ammonium salt group in combination with N-halamine group can reinforce the antibacterial activity. The chemical structure of as-synthesized N-halamine precursor 4-(Bromo-acetic acid methylester)-4-ethyl-2- oxazolidinone (BEO) was characterized by 1H-NMR. The cellulose fibers were characterized by Fourier transform infrared spectra and X-ray photoelectron spectra. The spectra data confirmed that the quaternarized N-halamine-grafted cellulose fibers were successfully obtained. The antibacterial properties of functional fibers were challenged with both Gram positive and Gram negative bacteria. The antibacterial tests and showed that the as-prepared antibacterial cellulose fibers exhibited powerful and rapid bactericidal performance against both Gram negative E. coli and Gram positive S. aureus. © 2015 Wiley Periodicals, Inc.
