在低温等离子体及低能离子作用下PET表面氮的XPS研究

经X射线光电子能谱(XPS)分析,在空气等离子体和氩等离子体作用下,(PET)表面上结合了不同的氮化合物。特别是在氩等离子体作用5min以后,N₁₅出现双峰,表明PET表面上结合了氮的氧化官能团。通过低能氮离子和氩离子轰击PET表面的实验,证明这种N₁₅双峰结构不是低能离子单独作用引起的。 关键词：

XPS STUDY OF SURFACE NITROGEN ON PET ACTED BY LOW TEMPERATURE PLASMA AND LOW ENERGY IONS

ESCA analysis identifies that the different functional groups of nitrogen compounds have been conbined on the PET surfaces, when modified by the air plasma and the argon plasma. In particular, the double N₁₅ peaks occur on the PET surface after 5 minutes treatment by the low temperature argon plasma. The second peak-N₁₅ is considered as the contribution of nitrogen oxides. The double peaks PET-N₁₅ structure does not result by bombardment with low energy nitrogen ions and argon ions, which indicates that the effect can not be attributed to the action of low energy ion alone.
