Abstract
Microporous structure of anodized alumina films formed in an acid electrolyte has been duplicated to other materials in high fidelity. In anodic oxidation of aluminum, the size and number of the micropores can precisely be controlled by the applied voltage, the kind and the concentration of the electrolyte used. The duplication of this microstructure is established by either electrodeposition of metals, chemical deposition of metals, sol-gel method or replica method using polymerization of resin.
The duplicated materials can be applied to the functional electrodes, optical grating film, microfilters or columnarly blent composite resin.
