A sandwich porous alumina nanostructures based on anodic alumina

الملخص EN

A sandwich porous anodic alumina membrane (PAA/Al/PAA) films was produced using two-step iodization 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.

Iodization on both sides of aluminum sheet was achieved.

The iodization 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.
