| 摘 要： | 采用CH4/CF4混合气体等离子体来处理PET表面.利用变角XPS研究改性后PET的表面改性层的组分随取样深度的变化.结果表明,碳氟混合气体等离子体在PET表面形成交联网络结构的改性层,改性层的化学组成随深度的变化不大;纯CF4等离子体的改性层的化学组成不均匀,含氟基团主要分布在外面.不同混合气体等离子体在PET表面形成改性层的结构决定于CH4的添加量.

| Abstract: | The surface of PET was modified by fluorocarbon plasmas.Angle\|dependent XPS technique was employed to study the surface structure and compositions of the modified layer on PET surface. It was found that the homogeneous, cross\|linking modified layer on PET surface can be formed by CH\-4/CF\-4 plasmas, and their composition change a bit with the increase of the sampling depth of XPS. However, for pure CF\-4 plasma, the modified layer is heterogeneous, and the amount of the fluorine\|containing groups on the outmost modified layers is more than that in the inner layer. The structures of the modified layer on the modified PET surface depend on the molar amount of CH\-4. The relationship between the compositions of the modified layers and the sampling depth will be discussed in details in this paper. |
