Anodic Aluminum Oxide (AAO) nano membrane fabrication under different conditions

This paper presents research on the AAO membranes: its fabrication process, comparison and analysis of the results obtained under different conditions. For this research three types of aluminum sheets were used (based on purity), and on each type of aluminum sheet AAO membrane had been grown. The process include: cutting of Al sheet, cleaning in acetone and DI water, annealing, electro-polishing, first step of anodization, alumina etching, second step of anodization, aluminum etching and finally testing with Scanning Electron Microscope. Two types of anodization processes have been used for this research: mild anodization and hard anodization. Both process tested for three different type of Aluminum sheet for different time duration and finally results were obtained as SEM image has been compared and analyzed.
