The Surface Morphology And Structure Of Fluorocarbon Films Deposited On PET Substrate

Fluorocarbon films are deposited by radio frequency magnetron sputtering polytetrafluoroethylene(PTFE) targets on polyetylene terephalate(PET) substrate to examine the effect of discharge condition on the surface structure of the deposited films.The effect of the power > pressure and treating time on morphology is observed by means of Scanning Electron Microscopy ( SEM ) .It is found that the fluorocarbon film particles distribute more uniform and join tightly with the increasing of power, the surfaces of films become closer and denser when pressure increases. The clusters grow into island, then films, not growing into monolayer when treating time increases.The equilibrium of the fluorocarbon films is investigated with SEM and X-ray photoelectron spectroscopy (XPS) .It is found the films are not well distributed. This maybe has something to do with our deposited chamber. This has not been reported by others.Nano-material self-assembly structure is firstly analysed with SEM > Atom Force Microscopy ( AFM), X-ray diffractometry.lt is found the fluorocarbon films aren't all amorphous. They may be ordered at some condition. This has not been reported by others.
