Haloamines have advantages as highly efficient bactericidal, relatively inexpensive synthesis, non- toxic, environmentally friendly and unique reproducibility. In this study, UiO-66-NHCl bacteriostatic material was prepared by introducing reactive chlorine bonding groups based on zirconium-based metal-organic skeleton-UiO-66-NH2, and PET fibers were coated by impregnation method. When the content of reactive chlorine in UiO-66-NHCl bacteriostatic material was 8%, the impregnation time was 6 h, and the drying temperature was 60oC, the maximum amount of UiO-66-NHCl load on PET fibre. We analyzed the PET fibers coated with UiO-66-NHCl antibacterial material by XRD, SEM, FT-IR, EDS and XPS characterization, and tested the stability, biosafety and performance on antibacterial properties of the material. The results showed that the UiO-66-NHCl@PET composite fiber remained 91% and 83% of the original chlorine content after 30 days of storage and shaking, and the stability of the material was good. Meanwhile, the composite fiber inhibited both S. aureus and E. coli, and the diameter of the inhibition circle was >7 mm, in which the inhibition activity of S. aureus was better than that of E. coli. The UiO-66-NHCl@PET composite fiber has better inhibitory activity against S. aureus than E. coli, with excellent antibacterial performance and no irritation. The results can help to provide theoretical support for the production of medical protective equipment with excellent protection effect. [ABSTRACT FROM AUTHOR] |
