Nanoporous templates with different geometry for nanostructured metal coatings
The method consists of the following steps (Figure 1):
1. Starts from high purity aluminium laminates.
2. The mold (CD,DVD and BR discs) is pressed onto the laminate, printing the predefined pattern of the particular disc on it. This process can be performed multiple times, changing the print angle to obtain templates of different geometry (cubic, triangular, rhombus symmetry).
3. By means of an electrochemical anodizing process the aluminium is oxized and by self-assembly originates a template with ordered nanopores respecting the pattern previously printed.
4. By sputtering on the surface is obteined a metal coating that respects the aforementioned pattern.
In particular, it allows the production of metal nanostructures os different ferromagnetic materials of high applicability.
Industrial partners from the nanotechnology are being sought to collaborate through a patent license agreement.
