We have studied porous anodic alumina template through the second anodic oxidation of preparation. Observing the morphology of nanoscale AAO template using scanning electron microscope (SEM), the results indicate that the pores are orderly paralleled arranged with uniform pore diameter, perpendicular to the template surface. A detailed study of the influence of different oxidation conditions, such as different type of electrolyte, concentration, voltage and temperature on the template of alumina and its electrochemical mechanism were performed. By changing the oxidation voltage, electrolyte type, concentration, pore diameter and template thickness can be altered in a wide range such that we can obtain the desired aspect ratio. <br>

Anodic Alumina Template

Various porous alumina structures are formed in different electrolyte systems. Adjusting the anodizing parameters can yield different apertures and regularities of the porous alumina template. Thus, porous alumina is widely applied in the preparation of ordered nanostructured materials. This study introduces the porous alumina structure, including its formation mechanism, manufacturing technology, and application in the manufacture of nanostructure materials.
