Fabricating Anodic Aluminum Oxide by Anodic-Oxidation

Ji Yan He, Jian Ren, Yan He

Abstract

Uniform parallel pores and controllable pore diameter make Anodic Aluminum Oxide (AAO) membrane one of the best materials in synthesis of one-dimensional nano-structured material. High orderly AAO template was prepared by anodic-oxidation. The prepared AAO membrane’s apertures ranged from 30 nm to 75 nm. Within a few microns, holes were orderly arranged. The fabricating methods of AAO template in different electrolyte were studied and the factors which affect the pore distribution, such as electrolyte types, voltage and concentration were discussed.
