The ZnO (zinc oxide) functional thin films were deposited on PET (polyester) spun-bonded non-woven by DC (direct current) reactive magnetron sputtering through the reaction of Zn with O2. XRD (X-ray diffraction) revealed the existence of ZnO and the polycrystalline with hexagonal crystal structure of the deposited ZnO film. The deposited ZnO showed a strongly preferred orientation of c-axis perpendicular to the substrate surface. The sputter coating of ZnO significantly altered the surface microstructures of the PET fibers examined by Atomic Force Microscope (AFM). The bonding between the sputtered ZnO and PET fibers was observed by Scanning Electron Microscope (SEM). The results of the UV/Visible spectrum indicated the transparent and ultraviolet (UV) absorption properties of the sputtered ZnO films. The anti-static tests revealed that the sputter coating of ZnO significantly improved the anti-static function of the samples and the anti-static function also obviously enhanced as the deposition thickness increased.
