Bi‐functional antibacterial material was prepared by co‐grafting N ‐halamine and quaternary ammonium salt monomers from cellulose fiber. The grafted fiber was characterized by Fourier transform infrared spectra, and X‐ray photoelectron spectra. The N ‐halamine derived from the precursor 4‐[(acryloxy)methyl]‐4‐ethyl‐2‐oxazolidinone via chlorination treatment and the oxidative chlorine (Cl + ) leaching behavior were investigated. The antibacterial activities of singly (only QAs‐functionalized or only Cl + ‐releasing) and dual (QAs‐functionalized and Cl + ‐releasing) functional cellulose fibers were tested against Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus . Compared to singly functionalized formulations, the bi‐functional cellulose fiber exhibited excellent and rapid bactericidal performance against both E. coli and S. aureus . © 2013 Wiley Periodicals, Inc.
