摘要: 本工作应用ESCA研究了聚合条件对产物结构的影响,并着重讨论了在非辉光区中形成的等离子体聚四氟乙烯(PPTFE)膜的ESCA表征。发现在非辉光区中形成的PPTFE是近于线型的,并用X射线粉末照相证实,聚合膜具有类似普通PTFE的结晶结构,约有20条衍射环。另外,考察了放电功率、压力和等离子气体等对聚合膜结构的影响。

Abstract: We have studied the effects of polymerization conditions on the product structures and emphasized the ESCA characterization of PPTFE film formed in nonglow region. The results have shown the formation of a nearly-linear PPTFE in nonglow region. It has been found that the X-ray diffraction patterns of the PPTFE formed in this region are similar to those of chemically charge power, pressure and plasma gases on the structure of polymer films have also been examined.
