Influence of pretreatment on preparation of porous anodic alumina film

Research output: Contribution to journalArticlepeer-review

Abstract

The influence of annealing, degreasing, electropolishing on the morphology of porous anodic alumina was investigated. Experiments indicate that acetone exhibits the best degreasing effect and that well-arranged porous anodic alumina film is obtained without annealing and electropolishing. The preparation of porous anodic alumina film is simplified because of the two-step anodic oxidation method that eliminates the influence of disfigurement inside and on the surface of aluminium.
