摘　　要：以氩气/氧气混合气体(Ar/O2)为工作气体,通过常压低温等离子体技术对聚乙烯薄膜表面引发接枝丙烯酸改性,从而制备出一种超亲水聚乙烯薄膜,并用IR、AFM、接触角仪对其进行表征。结果表明:最佳工艺条件是85W、2min;两通装置优于单通;使用Ar/O2混合气体低温等离子体技术和丙烯酸接枝技术对聚乙烯薄膜进行改性效果优于使用单一Ar低温等离子体技术,前者接触角可降低至8.78±3°,并且可稳定在11.80±3°,具有良好的亲水性和耐久性。This research triggers the modification of grafted acrylic acid on the surface of PE film with normal-pressure and low-temperature plasma technique with argon/oxygen mixed gas（Ar/O2） as working gas, thus preparing a superhydrophilic PE film, and characterizes it with IR, AFM and contact goniometer. The result shows that the optimal process conditions are 85 W, 2 min; two-way device is better than one-way device; the effect of modification of PE film with Ar/O2 mixed gas low-temperature plasma technique and acrylic acid stem grafting technique is better than that with single Ar low-temperature plasma technique; the contact angle of the former can decrease to 8. 78±3° and stabilize at 11.80±3° it has a good hydrophily and durability.
