摘要: 一般根据膜衬底XPS峰强的衰减与膜厚的关系即可判断硬脂酸类LB膜的成膜质量,本文利用角分辨XPS技术,根据硬脂酸铜LB膜持征的羧基碳与样品中的总体碳Cls,蜂强度的比值(r)在不同电子出射角时的变化(△r),与无序粉末样品比较得出了成膜质量与△r间的对应关系,提出了一种利用XPS监测成膜质量的方法。

Abstract: In this article, angle-resolved XPS was used for the evaluation of copper stearate LB films. At the different take-off angles, the ratios(r) of carboxyl C1sintensities to that of the total carbon in the sample are different. Comparing the powder sample with the disordered structure, we got the relationship between the difference of r and the quality of LBfilms. Such a method was found to evaluate the quality of LBfilm with carboxyl hydrophilic head.

Key words: XPS, LB film, Take-off angle of electron
