Abstract
The self-repair of an ordered pattern of nanometer dimensions based on the self-compensation properties of anodic porous alumina is demonstrated. In a pretextured pattern formed on Al using the nanoindentation process with an array of convexes, the deficiency sites of the pattern were found to be co mpensated automatically during the anodization. Combining the self-compensa tion properties of the pore configuration of the anodic porous alumina with the preparation of a replica of the compensated porous structure allowed u s to develop a process which has the capability of self-repairing the imper fections in the starting pattern. It was confirmed that deficiencies in the starting pattern could be repaired automatically in the Ni pattern regener ated using the self-compensated anodic porous alumina as a template.
