采用磁控溅射技术,在丙纶(PP)非织造布基材表面沉积厚度为0.5～2 nm的银薄膜,研究氩等离子体预处理对PP基材沉积银薄膜后表面形貌和抗菌性能的影响.原子力显微镜(AFM)分析表明,经氩等离子体处理后的纤维表面有明显的刻蚀痕迹,沉积的银粒子分布均匀、不易团聚;X射线能潜仪(EDX)分析表明.经氩等离子体预处理后,PP非织造布表面沉积的银粒子总量增加,表面沉积1nm厚的银薄膜,对大肠肝菌和金黄色葡萄球菌的抑菌率分别达到99.96%和100%.

Magnetron sputtering coatmg technology is used to deposit silver films with different thicknesses ranging from 0.5 nm to 2 nm on PP nonwovens,and the effect of argon plasma pretreatment on surface morphologies and antibacterial prop-erties of the coated nonwovens is studied. The surface morphologies of PP nonwovens before and after plasma treatment are observed. The AFM (atomic force microscope) images show that the process of argon p～asma treatment results in the forma-tion of obvious etch dot and flute on PP fibers,thus the sputtered silver particles are uniform distribution and hard to cluster.EDX (energy dispersive X-ray) analysis indicates that after plasma pretreatment,the overall amount of silver ions deposited on PP nonwovens is increased. Silver film with 1 nm thickness on PP nonwovens has good antibacterial properties of 99.96% and 100% to E. coli and Staphylococcus Aureus respectively.
