Study of nanostructure and uniformity of fluorocarbon films prepared on PET substrates

In order to research and develop waterproof moisture permeable PET fabric,fluorocarbon film was prepared on PET film and fabric by magnetron sputtering.Nanostructure and homogeneity of fluorocarbon film were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS).SEM shows that fluorocarbon film is in good orientation under certain conditions and has a character of network and rod-shaped nano self-assembly.Network structure of film was obtained for development of waterproof moisture permeable fabrics.It is indicated by XRD that fluorocarbon film is partly crystallized.XPS shows that the ratio of F/C increases with the pressure increase.
