Currently, due to the development of nanotechnology and metamaterials, it has become important to obtain regular self-organized structures, with different parameters. Porous anodic alumina films are self-organizing structures, which can be represented in a hexagonal packing of cylindrical pores normal to the plane of the aluminum film and used as a template for synthesis of various nanocomposites. The diameter of pores and the distance between them can vary (pore diameter — from 2 to 350 nm, the distance between the pores — from 5 to 50 nm), using different electrolytes, voltage and anodizing time. Currently, there are various models that describe the growth of a porous film of aluminum oxide, but none take into account the influence of aluminum layers and electrolyte on the rate of aluminum oxide growth, as well as the effect of
surface diffusion. In present work we consider those effects.

Keywords: porous aluminum oxide, anodizing, anodized aluminum oxide.
