| Abstract: |
| In order to further study the fabrics and properties of porous anodic alumina membranes, EIS of anodic alumina membranes formed on different technical conditions were measured and analyzed by electrochemistry synthetical analysis instrument. The equivalent circuit models corresponding to these anodic alumina membranes were established. The result shows that the anodic alumina membranes produced in oxalic acid or phosphoric acid electrolyte are porous double-layer films. The equivalent circuit models of the anodic alumina membrane made via direct current electrical source in vitriol electrolyte have ' t the information of porous layer. Since EIS of anodic alumina membranes are different formed in different electrolytes and by different DC, AC and impulse electrical sources, so the equivalent circuit models simulates according to them made some differences. |
