摘要： 利用CF4与cH4/CF4等离子体来处理涤沦膜(PET),讨论了不同摩尔比的碳氟等离子体改性PET表面的作用机制.利用变角x光电子能谱(XPS)和接触角测试技术研究了改性后PET表面的结构和性质.结果表明,碳氟等离子体的处理可以显著地改善PET表面的憎水性.不同摩尔比的碳氟混合气体的作用机制不同,其中碳氟混合气体等离子体以聚合为主,在PET表面形成均匀的改性层;而纯CF4气体则以刻蚀为主,含氟基团主要分布在PET表面.

Abstract: Poly(ethyl terephthalate)(PET) surfaces were modified by CF4 and CH4/CF4 plasmas in this paper. The angle-dependent X-ray photoelectron spectroscopy(XPS) technique was employed to determine the changes of surface structures and properties of the modified PET. The surface modification mechanisms on PETby the fluorocarbon plasmas at different molar ratios were detailed discussed. Experimental results show that hydrophobic characteristic of the modified PETsurface can be improved by fluorocarbon plasmas singnificantly. CH4/CF4 mixture plasma is polymerization predominated, and the homogeneity along depth of surface layers can be intuitively observed. On the other hand, pure CF4 plasma is etching prodominated, and the fluorine-containing groups distributes on the modified PETsurface.
