| Abstract: | Porous aluminum oxide (PAO) templates were prepared by anodization of Al sheets in sulfuric,phosphoric and oxalic acid aqueous solutions.The porous alumina layers were detached from the Al substrate by using anodizing voltage decreasing method.The results of transmission electron microscopy (TEM) study s howed that this kind of the pore distance,pore diameter,and the cell sizes wer e increased with the applied anodizing voltage.Incorporation of anion ions of a nodizing electrolytes in the formation of porous membrane during the anodization procedure was found with the IR transparent spectra method.The XRD spectra of the membrane showed the formation of amorphous aluminum oxide. |
