摘　　要：用空气中介质阻挡放电(DBD)产生的常压低温等离子体对聚对苯二甲酸乙二酯(PET)薄膜进行表面改性。通过扫描电子显微镜 (SEM)观察、接触角测量和X射线光电子能谱分析 (XPS)等手段研究了DBD处理前后PET的表面特性。试验结果表明 ,PET表面经DBD等离子体处理后 ,其表面微观样貌和表面化学成份均发生变化。经DBD处理10s后 ,PET的表面含氧量增加到35 % ,表面水接触角降到37°。The surface of PET film is modified using non-thermal plasma generated by the dielectric barrier discharge(DBD)at atmospheric pressure in air.The effects of DBD on PET surface modification are studied,and the surface properties before and after the DBD treatment are characterized by contact angle measurement,x-ray photoelectron spectroscopy(XPS)and scanning electron microscopy(SEM).It is found that the DBD treatment modifies the PET surface in both morphology and composition.After10s DBD treatment,the surface oxygen content of PET surface increases to35%,and the water contact angle decreases to37°.
