TI  - Uniform and reproducible barrier layer removal of porous anodic alumina membrane.
PG  - 3380-4
AB  - A method for the fabrication of porous anodic alumina (PAA) membrane without 
      bottom barrier layer on Al substrate is described. In this method, two-step 
      anodizing followed by a barrier thinning process at the end of the second 
      anodization was used to prepare wide range highly-ordered PAA membrane with a 
      thin barrier layer. Finally, cathodic polarization and pore widening processes 
      were combined to remove the barrier layer completely between the oxide film and 
      Al substrate. Scanning electron microscope (SEM) was used to characterize the 
      morphology and structure of the PAA membrane. From the SEM images, the PAA 
      membrane prepared with the assistance of cathodic polarization showed more 
      homogeneous pore diameters and pore wall quality than that made by pore widening 
      only. In addition, the barrier layer was removed completely with 7.5 min of 
      cathodic polarization and 70 min of pore widening without corrosion in the Al 
      substrate. It was possible to control the pore diameter without any damage to the 
      PAA template from 70 to 90 nm. The fabricated PAA template can be applied to the 
      growth of ordered nanowires, nanorods, nanotubes, and similar structures.
