摘要
在室温条件下采用射频磁控溅射方法,在纯棉机织物表面沉积TiO2功能纳米结构层.利用原子力显微镜和X射线衍射仪分别分析其表面形貌和晶态结构,同时对负载纳米TiO2织物的抗菌性和耐洗性进行了初步研究.实验表明,在拟定的溅射工艺条件下,纯棉机织物表面沉积了晶粒较为均匀、粒径较小的锐钛矿型纳米TiO2功能结构层,这一功能层使负载织物呈现出优良的抗菌性能;同时负载织物具有良好的耐洗性,经30次洗涤后,其抗菌性能仍保持在很高的水平.
Nanoscale titanium dioxide （TiO2） functional films were deposited on the surface of cotton fabric by RF magnetron sputter coating process. The surface microstructure and morphology were characterized by Atomic Force Microscope （AFM） and X-ray diffraction （XRD）. The results showed that the nanoscale titanium dioxide deposited on the surface of the treated cotton fabrics is at different anastasia phase. The particles of titanium dioxide had diameters in nano meter and distributed uniformly on the surface of cotton fibers. It was found that the coated fabrics shows excellent antibacterial property, and after 30 launderings, the antibacterial activity still maintained at a high level.
