Abstract

Highly ordered and highly density nanopore arrays of anodic aluminum oxide template was prepared by a two-step anodization method and with the assistance of ultrasonic. Well-aligned nanopore arrays were obtained perpendicular to the surface of aluminum. The first step anodization was carried out under 0.4 M oxalic acid for one hour, and the anodized film was removed by chemical etching, than the sample was anodized again for 40 minute under the same conditions as the first anodization and with ultrasonic. The results of aluminum oxide films were characterized by scanning electron microscopy, and the microstructure of the anodic aluminum oxide membrane indicating that the nanochannel arrays prepared with the assistance of ultrasonic are better than those in ordinary way related to the pore aligned and pore density.
