为了实现纺织材料表面抗菌功能化,采用低温磁控溅射技术在真丝织物表面沉积1~5nm厚的纳米结构银薄膜。采用振荡烧瓶法测试样品的抗菌性能;利用原子力显微镜(AFM)分析了纳米银薄膜的表面形态和粒径。结果表明:在实验范围内,1nm厚的银膜已具有优良的抗菌性能。从纳米银薄膜表面形态结构可以看出,纳米结构银薄膜由极其微小的均匀性较好的粒子组成,基本呈连续覆盖状态,随着溅射时间的延长,纳米银颗粒存在一定团聚现象,粒径呈增大趋势。X射线衍射(XRD)测试表明,沉积在丝织物表面的纳米银薄膜形成了一定结晶结构。
In order to achieve the antibacterial function of the surface of textile materials, low temperature magnetron sputtering technique was used to deposit nanostructured silver thin films with a thickness of 1 ~ 5nm on the surface of silk fabrics. The antimicrobial properties of the samples were tested by oscillating flask method. The surface morphology and particle size of the nanosilver films were analyzed by atomic force microscopy (AFM). The results show that: in the experimental range, 1nm thick silver film has excellent antibacterial properties. It can be seen from the surface morphology and structure of nanosilver thin film that the nanostructured silver thin film is composed of extremely fine and uniform particles with a substantially continuous coverage. With the extension of the sputtering time, the nanosilver particles have a certain agglomeration phenomenon, Path is increasing. X-ray diffraction (XRD) test shows that the deposited nano-silver film on the surface of the silk fabric has a certain crystalline structure.
