Porous films and method of forming them. |
摘要 |
<p>An anodic aluminium oxide film (12) has a system of larger pores (14) extending in from one face (16) and interconnecting with a system of smaller pores (24) extending in from 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 the oxide film, either continuously or incrementally in small steps down to a level preferably below 3 V, and separating the oxide film from the substrate.</p> |
