Abstract
The object of this work is to develop a novel approach to fabricate model membranes of well-defined and well aligned nanostructured materials in a robust environment. The main focus is on electrochemical synthesis, involving anodic oxidation of high purity aluminum sheets to form porous oxide films. Alumina films were prepared by anodizing highly pure aluminum (99.999%) in acidic electrolytes. Anodization parameters (current density, temperature, applied voltage, anodization time and electrolyte concentration) were selected with respect to the electrolyte used.
The primary challenge in nanotechnology is the creation of nanometer-scaled objects with as narrow a size distribution as possible for a desired size and shape and with as perfect a crystalline structure as possible. In particular, the creation of a nanostructure with a fine pattern and nanorods with a high degree of alignment and aspect ratio has become a promising approach in the development of nanotechnology applications. In this research we implemented an Anodic Aluminum oxide nanotemplate based structure to achieve this goal. An AAO template has a fine hexagonal structure, and its aspect ratio is readily controllable by controlling the anodization parameters, In this report, controllable diameter fabrication of AAO templates at room temperature was studied, and its applications in synthesizing nanorods were explored.
