Abstract

Nanoporous alumina was synthesized using 0.7mm thick aluminum sheet via two-step anodization carried out at 40V, 14°C with 0.3M oxalic acid as electrolyte. The arrangement of pores was primarily affected by polishing the sample prior to anodization. Polished aluminum sheet produced a regular pore array with 38nm mean diameter and 115nm interpore distance. Pore size was seen to increase with etching time.
