  Porous anodic alumina membrane (PAAM) is widely used as a template for its advantages of the highly controllability and regularity.In this report, one kind of new double-faced PAAMs was fabricated with the three-step anodization method.Firstly, the annealed aluminum foil cleaned with acetone and alcohol was electrochemical polished at a constant voltage of 3 V in a mixture of chromic acid and phosphoric acid and Sulfuric acid at 60 ℃ for 20 min.
