PREPARATION AND CHARACTERIZATION OF PET NONWOVEN COATED WITH ZnO-Ag BY ONE-POT HYDROTHERMAL TECHNIQUES

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
