【摘要】：本文采用二次阳极氧化方法制备了多孔阳极氧化铝模板,同时制备了三角形、正方形、管状多孔阳极氧化铝模板,利用扫描电子显微镜(SEM)和X射线衍射仪(XRD)研究了其形貌与结构,结果表明多孔阳极氧化铝膜为非晶态结构,其孔洞呈有序排列,孔径均匀,约为65nm。另一方面,研究了高温退火对多孔阳极氧化铝膜形貌的影响,结果发现多孔阳极氧化铝膜含有铝元素；当退火温度在900℃及以下,其形貌没有明显的变化,但当退火温度达到1100℃时,其表面却出现了熔化现象；多孔阳极氧化铝膜的结晶温度很大程度上取决于其厚度。 以阻挡层经过薄化处理的多孔氧化铝为模板,采用恒压电沉积法成功制备了有序Cu纳米线阵列,并用SEM、XRD等对该阵列进行了结构分析。结果表明Cu纳米线为面心立方结构,直径约为65nm,长度约为15μm,与所用多孔阳极氧化铝模板一致。
[Abstract]:In this paper, porous anodic alumina templates have been prepared by secondary anodizing method, and triangular, square and tubular porous anodic alumina templates have been prepared. Scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used to study the morphology and structure of the films. The results show that the porous anodized aluminum oxide films are amorphous, the pores are arranged in order and the pore size is about 65 nm. On the other hand, the effect of high temperature annealing on the morphology of porous anodized aluminum film was studied. It was found that the porous anodized aluminum film contained aluminum element. When the annealing temperature is below 900 鈩，
