聚丙烯薄膜表面的大气压等离子体处理可以显著增加其表面能，从而改善薄膜的可印刷性。因此，实验室规模的介质阻挡放电（DBD）系统，它模拟了电极配置和卷轴到卷轴的网络传输机制中使用的一个典型的工业规模的系统。通过在氮气放电中处理聚丙烯，我们已经表明，与未处理的薄膜相比，水接触角可以降低多达40°，相当于表面能增加14 mNm−1。油墨拉脱试验表明，DBD等离子体处理导致溶剂型油墨对聚丙烯膜的优异粘附性。
Atmospheric pressure plasma treatment of the surface of a polypropylene film can significantly increase its surface energy and, thereby improve the printability of the film. A laboratory-scale dielectric barrier discharge (DBD) system has therefore been developed, which simulates the electrode configuration and reel-to-reel web transport mechanism used in a typical industrial-scale system. By treating the polypropylene in a nitrogen discharge, we have shown that the water contact angle could be reduced by as much as 40° compared to the untreated film, corresponding to an increase in surface energy of 14 mNm−1. Ink pull-off tests showed that the DBD plasma treatment resulted in excellent adhesion of solvent-based inks to the polypropylene film.
