Forming complex geometry of nanopore by anodic oxidation of aluminum by pulsation method

Anodic oxide self-ordered nanoporous films are now widely used in various fields of science and technology. However, there is a request that the nanopores in these oxides be not only direct and plane-parallel, but also have a certain geometry. It is understood that it is necessary to change the geometry of the pores with different thickness increments and branching nanopores. To solve this problem, the method of pulsed anodizing with direct current in a complex electrolyte with organic additives is used. In addition, other changes in the parameters of the anodizing process.
