摘要

高聚物界面的能量、结构等性质

对理论研究和实际应用都是极为重要的．因为许多聚合物材料都具有一个或多个界面的多相结构

这些界面的结构和强度等

显著地影响着这些多相材料的物理、力学性能等

而它们之间的关系

是一个极为复杂的问题

只有综合界面科学、流变学、应力分析和断裂力学等诸学科才能解决之．在高聚物材料表面性质的诸多测量技术

如ＸＰＳ、接触角法、扫描电镜（ＳＥＭ）

全反射红外（ＡＴＲ）中

接触角?...

Abstract

The Poly(ethyl terephthalate) (PET) surfaces were modified by fluorocarbon plasmas.Angle dependent x ray photoelectron spectroscopy (XPS) and contact angle techniques were employed to determine the change of the surface structures and properties of the modified PET.Experiments show that the changing of F/C ratio and contact angle of the modified PET along with the CH 4/CF4 feed.It was found that the modified surfaces show more hydrophobic

and CF 4/CH 4 plasma exhibits more stronger hydrophobic effect than CF4plasmas alone.The structures and properties of the modified PET surface depend on the molar ratio of the CH4/CF4 feed.The plots of contact angle vs.molar ratio of the CH4/CF4 feed is the same with that of F/C ratio measured by angle-dependent XPS at 10 degree of taking-off angle.By conparison

the relationship of the sampling depth of XPS and contact angle can be obtained.
