Abstract
Abstract The mesoporous anodic alumina(AA) membrane with highly ordered arrays of uniform nanohole was prepared by anodic oxidation process in an aqueous solution of sulfuric acid at 20 C. Morphology, pore size, pore size distribution and thickness for mesoporous AA membrane was examined with several anodizing conditions; reaction temperature, current density, electrolyte concentration, amount of additive, etc. The pore density in the array was approximately 3.5-5.8 X 1014 m-2 with pore diameter and membrane thickness of approximately 25-35 nm and 50 m.
