Effect of duration on pore widening of one-step anodized aluminum oxide template

Abstract

This work investigated the effect of pore widening for fabrication of anodized aluminum oxide (AAO) template. AAO template was fabricated using one-step anodization method. The influence of H 3 PO 4 on the widening of pore of AAO was investigated. The morphology of AAO was analyzed using FESEM. Result shows that by widening the pores at 25°C can help to protect the neighbouring pores from any damage. Single, well separated, straight without any tilt or branches, well aligned and controllable pore diameter could be obtained using this technique.
