本文通过真空蒸镀法制备得到含银型高密度聚乙烯(HDPE)基抗菌复合膜(Ag_2O/HDPE),利用原子力显微镜、扫描电子显微镜及原子吸收光谱法测试手段对膜进行了表征,并考察了复合膜的抗菌动力学和抗菌长效性,以及对细菌的黏附性. 结果表明,HDPE上的银离子含量为7.0020μg/cm~2,无机镀层厚度为17.2 nm. 抗菌实验发现,复合膜能在3 h内将大肠杆菌和金黄色葡萄球菌全部杀死,并且无机镀层能在一定程度上提高膜表面平滑度,减少细菌在膜表面上的黏附量. 但由于无机镀层与HDPE基膜的结合力不够强,该膜不具有抗菌长效性

The Ag2O layers were coated by vacuum evaporation on as-deposited high density polyethylene(HDPE) sheets, 120 μm in thickness. The microstructures and antibacterial properties of the composite Ag2O/HDPE films were characterized with atomic force microscopy, scanning electron microscopy and atomic absorption spectroscopy. The results show that the Ag2O/HDPE composite film displays excellent antibacterial activities against a variety of bacteria, such as Escherichia coli, and Staphylococcus. For instance, the composite films wiped out the germs ...
