Abstract

Large size anodic alumina film has not been used in the industry due to that the fabrication parameters are very difficult to control, but the fabrication of large size anodic alumina is exigent as a template in the fabrication of diverse nano-devices oriented to the industrialization. In this paper, large size (width length = 80 mm × 80 mm) porous ordered anodic alumina film was fabricated by using two-step anodization process as compared to the small size (diameter = 40 mm) anodic alumina film in the structures. Pore size and film thickness of anodic alumina film are strongly related to the size of the anodization film. The large size anodic alumina film has an ideally ordered pattern by applying low voltage. However, with the increase of voltage, the ordered pattern of the PAA films was gradually disrupted, especially in the 70 V due to the local thermal imbalance.
