The effect of temperature and concentration on the self-organized pore formation in anodic alumina

Abstract

Nanosize pore arrays, which have been prepared by the self-organization process of aluminium anodic oxidation, were investigated quantitatively using fast Fourier transformation analysis of scanning electron microscopy micrographs. The results show that the temperature influences the pore domain size and the best self-ordering configuration is obtained at an optimum condition of temperature. The largest domain size was observed for samples anodized around 15°C to 17°C, using 0.3M oxalic acid. It is also found that the optimum temperature for self-organization of pore oxidation changes in accordance with the concentration of electrolyte.
