涤纶基材表面沉积Ag/ZnO复合膜形貌结构及性能研究

以组织结构不同的纯涤纶非织造布、机织布、针织布作为基材,采用直流射频共溅法,在织物表面沉积Ag/ZnO复合膜,通过扫描电子显微镜、X射线衍射仪、X射线光电子能谱仪对镀膜织物的表面形貌以及结构成分进行分析,测试了镀膜织物的抗静电、抗紫外线性能。结果表明:沉积Ag/ZnO复合膜后,机织布表面最不平整,针织布表面最平整;纯涤纶非织造布的结晶度较低。X射线光电子能谱表征证明Ag以单质形式存在于纯涤纶非织造布表面;纯涤纶非织造布的抗静电性最差,针织布最好;机织布抗紫外线性能最好,纯涤纶非织造布最差。

Study on the structure and property of Ag/ZnO composite film deposited on the surface of polyester substrate

The pure polyester non-woven fabrics,woven fabrics and knitted fabrics with different organizational structures were selected as the substrate.Firstly,the Ag/ZnO composite films were deposited on the surface of polyester fabric by DC/RF co-sputtering method.The surface morphology and structure of the samples were analyzed by SEM,XRD,XPS,and then tested the antistatic and anti-ultraviolet properties.The experimental results shown that the nanoparticles deposited on the surface of the woven fabric were the most uneven,and the surface of the knitted fabric was the most flat.The surface of the nonwoven fabric was Ag/ZnO composite.The crystallinity of the film was low.XPS characterization indicated that silver existed in elemental form.In the structural chromogenic test,the knitted fabric was the substrate with the smallest brightness.The nonwoven was the substrate with the worst antistatic property,and the knitted fabric was the best.The woven fabric was the substrate sample with the best UV resistance and the worst nonwoven.
