EFFECT OF ACID ELECTROLYTE CONCENTRATION ON GEOMETRIC PARAMETERS OF NANOSTRUCTURED POROUS ANODIC ALUMINUM OXIDE
An array of porous aluminum oxide samples was obtained by electrochemical anodizing at varying the concentration of oxalic acid in the range from 0,1 M to 0,5 M. It was found that a decrease in electrolyte concentration leads to a decrease in the pore diameter, pore length, and packing density.
