Abstract

A well-ordered porous anodic alumina (PAA) membrane was achieved by anodic oxidization of the aluminium electrode at constant voltages of 30-50 V in a solution of 0.3 mol·L^-1 H₂C₂O₄. A new electrical detachment process was carried out to detach the PAA membranes from aluminium base in the solution of HClO₄ and CH₃OH. The mechanism of the electrical detachment process and the factors of the pore diameter and thickness of the barrier layer were researched. A larger size of PAA (2 cm × 2 cm) was obtained with thickness of 30-100 μm and full-controlled open-hole pores. Compared with reported chemical process, the present method is more simple and rapid and free of metal ions residues. It is important for research of nanostructure assembling techniques.
