AFM images revealed that as the sputtering time was prolonged, the film thickness increased, the film became compacter, and the specific area of the film also increased, thus, the release rate of silver ions increased, which led to improved antibacterial properties. EDX test results indicated that increase in film thickness led to increase in silver weight percentage per unit surface, causing improved antibacterial properties. Moreover, when the film thickness was 1 nm, the inhibition percentage of Staphylococcus aureus and Escherichia coli were 100%.

结果表明：随着薄膜厚度的增大，样品抗菌性能提高；溅射时间延长，薄膜厚度增大，膜层的致密性改善，单位面积上的银含量增加，膜层表面积增大，银离子释放几率增大，是提高抗菌性能的主要原因；当纳米结构银薄膜厚度为1 nm时，对大肠杆菌和金黄色葡萄球菌的抑菌率均达到100%。

The silver nanoparticles modified by oleic acid were successfully synthesized by the replacement reaction of silver nitrate with metal sodium in decalin, and the reaction was achieved via ultrasonic irradiation.
