Outline of Final Research Achievements

Ordered anodic porous alumina through-hole membranes were prepared by two-layer anodization using concentrated sulfuric acid solution. Hole period in anodic porous alumina through-hole membrane could be controlled by adjusting anodization voltage. Ideally ordered porous alumina through-hole membranes could also be obtained by a combination of the pretexturing of Al and subsequent two-layer anodization. The obtained ordered through-hole membranes are expected to be used in various functional application fields.
