Formation of dense alumina nanowires from anodic alumina membranes

Dense alumina nanowire arrays were formed by a method that consists in a partial dissolution of the anodized aluminium oxide (AAO) membrane by chemical attack in 2 M H3PO4 during 45 minutes, as a step immediately following the second anodizing. During this procedure the pore walls are partially diss...

During this procedure the pore walls are partially dissolved by a controlled acid attack and the alumina nanowires arise as a consequence of this process, being the vertices of the hexagonal pores the origin of them. The thickness of them (40 nm) is slightly smaller than the diameter corresponding to the triple junction point of the membrane.
