为提高聚合物材料的表面润湿性,采用磁约束大气压阻挡放电对聚丙烯薄膜进行处理.通过接触角测量仪、原子力显微镜和X射线光电子能谱仪分析和表征了聚丙烯薄膜在不同处理条件下的表面性能.结果表明:与无磁约束阻挡放电相比,磁约束阻挡放电能更好地降低聚丙烯薄膜表面的水接触角,材料表面粗糙度更大,在试样表面引入的含氧活性极性官能团更多,使材料表面润湿性提高.因此,磁约束能增强气体放电的效果.
In order to improve the surface wettability of polymer materials, polypropylene (PP) films were treated by magnetic confinement atmospheric dielectric barrier discharge. The surface properties of the PP films at different treatment conditions were analyzed and characterized by contact angle tester, atomic force microscope, and X-ray photoelectron spectroscopy. The results show that compared with the barrier discharge without magnetic confinement, the magnetic confinement barrier discharge treatment can decrease the water contact angle of the PP films better and increase the surface roughness, and more active polar groups including oxygen are introduced on the PP film surface, which make the surface wettability increase. Thus, the magnetic confinement can enhance the effect of gas discharge.
