| Abstract: |
| The surface of filter paper was selective dissolved using NaOH-urea-ZnO (mass ratio of 8∶12∶0.25) aqueous solution. The effects of processing time and temperature on the mechanical properties of the paper were evaluated. The paper was characterized using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR). The content of ZnO in sample was measured by Atomic Absorption Spectrophotometer (AAS) and X-ray photoelectron spectroscopy (XPS). The oil-resistance and antibacterial properties of the produced paper were also investigated. The results showed that the tensile and burst strengths of the paper were 2 times higher than that of the original at an optimum processing condition. Meanwhile, the treated paper was completely oil-resistant within 24 h and demonstrated good antibacterial properties when exposed to Staphylococcus aureus. The residual zinc oxide content in the paper could meet the safety regulation of food packaging. The prepared antibacterial and oil-resistant paper has good potential to be packaging material. |
