摘要
用空气介质阻挡放电(DBD)和大气压辉光放电(APGD)产生常压低温等离子体,并用其对聚对苯二甲酸乙二酯(PET)薄膜进行表面改性。用扫描电子显微镜(SEM)、测量接触角和X射线光电子能谱分析(XPS)等手段,研究经APGD和DBD处理前后PET的表面特性。试验结果表明,PET表面经APGD和DBD等离子体处理后,其表面微观样貌和表面化学组分均发生变化。APGD的处理效果优于DBD,即APGD可以对PET表面进行均匀处理,在表面引入更多的极性基团,使接触角下降到更低值。经APGD和DBD处理10s后,PET表面的含氧量分别增加到39%和35%,表面接触角分别下降到19°和37°。
The surface of PET film is modified using plasma generated by the atmospheric pressure glow discharge （APGD） and dielectric barrier discharge （DBD） in air. The effects of APGD and DBD on PET surface modification are studied, and the surface properties are characterized by contact angle measurement, X-ray photoelectron spectroscopy （XPS） and scanning electron microscopy （SEM）. It is found that the APGD and DBD treatments can modify the PET surface in both morphology and composition. APGD is more effective in PET surface modification than DBD as it can modify the surface more uniformly, implant more polar groups into the surface and make the contact angle decline to a lower level. After 10s APGD and DBD treatment, the surface oxygen content of PET surface increases to 39% and 35%, and the water contact angle decreases to 19° and 37°, respectively.
