Abstract:
      Binary composites (MCC/MOF-5 and MCC/HKUST-1) and ternary composites (MCC/MOF-5/HKUST-1 and MCC/HKUST-1/MOF-5) were prepared by in-situ deposition of metal-organic frameworks (MOF-5 and HKUST-1) onto the surface of microcrystalline cellulose (MCC). FT-IR and XRD were used to characterize the chemical structures of the composites. The morphologies of the composites were observed by SEM. Escherichia coli (E. coli) was used as a test strain to evaluate the antibacterial ability by measuring the diameter of the inhibition zone. The results showed that the binary and ternary composites were successfully prepared. MOF-5 and HKUST-1 on the surface of MCC exhibited cubic and rod-like shape respectively. Due to the synergistic antibacterial effect of metal ions, the ternary composites had better antibacterial properties against E. coli than the binary composites. The antibacterial effect of MCC/HKUST 1/MOF-5 was better than that of MCC/MOF-5/HKUST-1 as the antibacterial capacity of Zn2+ was greater than Cu2+.
