Control Porous Pattern of Anodic Aluminum Oxide by Foils Laminate Approach

166-170Control porous pattern of anodic aluminum oxide, aluminum foils laminate approach, barrier removing free methoIn this research, a novel, much simpler, and low cost method to fabricate porous pattern of the anodic aluminum oxide (AAO) based on the aluminum foils laminate approach were carried out. During our experiments, it was found that the pores of the AAO grew only on the upper foil, bi-directionally from both the top and the bottom surfaces. Experimental results further indicate that the upward porous pattern of the upper foil is determined by the surface structure of the bottom surface of the upper foil. The porous pattern of AAO can be controlled by a pre-made pattern on the bottom surface. Furthermore, no barrier removing process is required in this novel laminate method
