摘要

设计智能等离子体放电实验系统，并通过高纯空气介质阻挡辉光放电(DBGD)等离子体对双向拉伸聚丙烯薄膜(BOPP)进行表面改性。利用接触角测试仪对样品表面进行接触角测量和固体表面能分析；利用傅里叶红外光谱仪表征BOPP膜表面的化学成分变化。结果表明，产生介质阻挡辉光放电的间隙与气体气压大小成反比，高纯空气介质阻挡辉光放电对改善BOPP膜表面的固体表面能效果明显，表面液体接触角显著变小，等离子体表面改性效果随处理时间和放电功率密度的增加而显著提升。通过对处理前后样品的傅里叶红外光谱分析，发现处理后的样品出现了新的C—O基团和C—H键等，薄膜表面化学结构发生了变化。

Abstract:

The intelligent plasma discharge system was designed and the plasma surface treatment of biaxiallyoriented polypropylene(BOPP)film was carried out with dielctric barrier glow discharge(DBGD)in high-purity air plasma.The surface contact angle was measured by the distilled water and Diiodomethane,andchanges of the chemical composition of BOPP were characterized by the Fourier infrared spectrometer.Theexperimental results showed that the gap for producing DBGD decreased with the increase of gas Pressure,thesolid surface energy of BOPP film treated by DBGD plasma was improved significantly.The surface liquidcontact angle decreases with the increase of treatment time and power density.The chemical reaction in BOPPsurface upon plasma treatment was characterized by the FT-IR measurement,new C—0 groups and C—Hbonds appeared in the treated BOPP films due to DBGD treatment.

Key words: intelligent plasma discharge experimental system high-purity air DBGD BOPP film surface modification
