| Abstract | ||
| A sandwich porous anodic alumina membrane (PAA/Al/PAA) films was produced using two-step anodization approach on both sides of (250) μm pure aluminum foil electrode as an anode. A single sheet of stainless steel or graphite was used as a cathode. Anodization on both sides of aluminum sheet was achieved. The anodization processes and pore formation were studied and discussed in this work. The produced alumina membrane (5-30) μm thick was analyzed using scanning electron microscopy (SEM). The SEM image shows the PAA membranes has a well-defined nanostructure. The average pore diameter reaches (25) nm. The produced Al 2O3 membrane growing on both sides of aluminum sheet was separated into a twin nano membrane. | ||
