摘要: 在室温条件下采用直流磁控溅射方法,在醋酸纤维素(CA)纳米纤维表面沉积纳米银(Ag)薄膜,采用扫描电子显微镜(SEM)和透射电子显微镜(TEM)对不同溅射功率的纳米银膜的形貌和微结构进行表征;利用X射线衍射分析了纳米银膜的结晶状态;同时研究了在不同溅射功率条件下制备的沉积纳米Ag膜复合纳米纤维的光学透射性能。实验结果表明:纳米结构银薄膜由极其微小的均匀性较好的粒子组成,随着溅射功率的增加,组成纳米Ag薄膜的Ag粒子尺寸增大,薄膜的致密性和均匀性增加;制备的Ag薄膜均呈面心立方的多晶结构,并且结晶性能随着溅射功率的增加而逐渐增加,抗紫外线透射能力明显增强。

Abstract: Nanoscale silver (Ag) functional films were prepared on the surface of cellulose acetate nanofiber at room temperature by DC magnetron sputtering process. The surface morphology and microstructure of silver films were characterized by scanning electron microscope and transmission electron microscopy. X-ray diffraction measurements were carried out to examine crystalline state of silver films.The transmission properties of the nanocomposite fiber with silver films prepared under different sputtering power were analyzed. The results showed that silver films was formed by nanosize and homogeneous particles. It showed that increase in sputtering power lead to increase in the dimension of silver particles as well as the evenness and compactness of films. The results showed that the particle diameters, crystal properties and ultraviolet absorption gradually increase along with the increase of sputtering power. The as-prepared silver films form face-centered cubic of polycrystalline structure. The ultra-violet(UV) absorption by nanofiber with silver films was enhanced by increasing the sputtering power.
