摘要：An anodic aluminium oxide film (12) has a system of larger pores (14) extendingin from one face (16) and interconnecting with a system of smaller pores (24) extending infrom the other face (26). The film is made by anodizing an aluminium metal substrate,
then reducing the applied voltage at a rate to permit partial or complete recovery of theoxide film, either continuously or incrementally in small steps down to a level preferablybelow 3 V, and separating the oxide film from the substrate.
