Özet
Surface functionalization of polyethylene terephthalate (PET) nonwoven was achieved by one-pot hydrothermal synthesis of zinc oxide (ZnO) and silver (Ag). The surface morphology and properties of the ZnO-Ag composites coated PET nonwoven were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR), respectively. The SEM observations revealed the formation of nanostructured deposition on the fiber surfaces. XRD patterns confirmed the deposition of ZnO-Ag composites on the surface of the PET nonwoven. The ZnO-Ag composites coated PET nonwoven demonstrated a remarkable improvement in ultraviolet shielding. The antibacterial properties of the ZnO-Ag composites coated PET nonwoven were also investigated and the experimental results indicated that there was about 94.5% reduction of Escherichia coli and 92.4% reduction of Staphylococcus aureus between the Zno-Ag composites coated PET nonwoven and control samples.
