Resumo: A nano-porous anodized aluminium oxide layer was synthesized using two step anodization process, in which the dents of aluminium formed in the first anodization step (one day) worked as the initial sites of the pore growth in the second anodization step (one hour). The influence of the voltage on the structure of aluminium oxide has been studied. For different anodization temperatures, it has been found that higher temperatures decrease the pore size, although lower temperatures yielded higher symmetry. The electrolyte used has high influence on the ordered pore domain size. Sulfuric acid generated very small pore sizes, phosphoric acid produced a very big pore size and the largest domain size was observed for samples anodized in oxalic acid.
