采用常压下产生的阻隔等离子体改善聚酯（PES）薄膜的表面性能和与木材的粘接性能。利用阻挡放电等离子体对PES膜表面进行改性具有广泛的应用前景。等离子体预处理引发并参与PES表面上的接枝、聚合或交联反应。这种表面改性方法清洁、干燥、生态且非常有效。提高聚酯薄膜的润湿性是提高水性胶粘剂与木材粘接力的必要条件。阻挡等离子体处理聚酯薄膜导致薄膜表面自由能的显著增加，并使聚醚砜薄膜-橡木与聚氨酯胶粘剂的粘接接头剥离强度增加。
A barrier plasma, created at atmospheric pressure, was used to improve the surface and adhesive properties of polyester (PES) film with respect to wood using polyurethane adhesives. The modification of PES film surfaces using barrier discharge plasma is attractive for various applications. Plasma pre-treatment initiates and participates in grafting, polymerization, or cross-linking reactions on the PES surface. This method of surface modification is clean, dry, ecological, and very efficient. The enhancement of the wettability of the polyester film was necessary for promoting higher adhesion to wood with water-based adhesives. The treatment of polyester films by barrier plasma led to a considerable increase in the surface free energy of the film and subsequently an increase in the peel strength of the adhesive joint of PES film-oak wood with polyurethane adhesive.
