Abstract
A technological procedure is developed for producing highly organized porous alumina. The procedure yields a foil surface with a roughness of 100 nm. Porous anodic aluminum oxide samples are prepared via the double electrochemical anodization of the resulting foil. The samples are studied via scanning electron microscopy, and statistical data on their pore sizes are collected. Samples of porous anodic alumina with an average pore diameter of 60 nm are obtained.
