介绍了低密度聚乙烯 (LDPE) 和双向拉伸聚丙烯 (BOPP) 薄膜表面层氧化的 X 射线光电子能谱研究结果。使用不同的起飞角（即 10°、30° 和 90°）进行分析；因此，检查层的深度分别为0.6、1.9和3.7 nm。研究发现，两种聚合物薄膜表面层的氧化过程相似。然而，当处理能量低于 5 kJ/m2 时，LDPE 薄膜的氧化程度较高，而当能量高于该值时，BOPP 薄膜的氧化程度更高。 X 射线光电子能谱 (XPS) 检测到，两种聚合物在处理过程中都会从薄膜表面解吸氧气。
The results of an X-ray photoelectron spectroscopic investigation of the oxidation of surface layers of low-density polyethylene (LDPE) and biaxially oriented polypropylene (BOPP) films are presented. The analysis was performed using different take-off angles, namely 10°, 30°, and 90°; thus, the depths of the examined layers were 0.6, 1.9, and 3.7 nm, respectively. It was found that the course of the oxidation process in the surface layers was similar for both polymer films. However, for treatment energies lower than 5 kJ/m2, the extent of the oxidation was higher for the LDPE film, whereas for energies above this value, the BOPP film was more oxidized. As detected by X-ray photoelectron spectroscopy (XPS), desorption of oxygen from the film surface occurs for both polymers during the treatment.
