Grafted antimicrobial cotton fabrics with N-halamine groups via atom transfer radical polymerization

An N-halamine precursor 2-(3-(6-methyl-4-oxo-1,4-dihydropyrimidin-2-yl)ureido)ethyl methacrylate (SCMHBMA) was synthesized and grafted on cotton fabrics via atom transfer radical polymerization for antibacterial function after chlorination. The preparation chlorinated (Cotton-g-PSMA-Cl) were characterized with FTIR, XPS, SEM, TGA. properties of prepared Cotton-g-PSMA-Cl, including thermal property, efficiency, durability, stability, systematically evaluated. results showed that these Cotton-g-PSMA-Cl possessed excellent activity against E. coli. S. aureus. After 10 washing cycles 60 days routine storage, active chlorine concentrations (Cl+%) reduced only 22% 18%, respectively, the Cl+% effectively reverted by simple rechlorination. This new composite superior exhibited potential future application in long-term field.
