Porous Anodic Alumina (PAA) was prepared by two-step anodization on both sides
of an aluminium foil. The anodization carried out at anodizing temperature 17oC using
oxalic acid as an anodizing electrolyte. The (PAA) template was characterized with
optical microscope and SEM. The optical microscope image showed two (PAA) layers
after the dissolution of the residual aluminium. The average pore diameter was found to
be (75) nm. The average interpore distance of (PAA) prepared was found to be (99) nm.
The thickness of (PAA) was found to be (59.5) μm.
