Abstract

Zr-Al₂O₃ composite oxide films are promising dielectric materials for future use in aluminum (Al) electrolytic capacitors. The films were prepared on etched Al foil samples by ZrO₂ sol-gel coating and anodizing. To inhibit O₂ evolution during anodization, 2-methyl-1, 3-propanediol (MPD) was used with boric acid solution as an electrolyte. In this study, we investigated the effects of the ratio of MPD in boric acid solution on the anodizing behaviors and electrical properties of ZrO₂-coated Al foil. The thickness of the Al₂O₃ layer decreased as the MPD ratio increased. The MPD-boric acid solution effectively inhibited O₂ evolution. The samples anodized in MPD-boric acid electrolyte with a ratio of 3:10 (volume %) exhibited the highest specific capacitance. Relative to those of samples anodized in boric acid solution, the specific capacitances of samples analyzed in the MPD-boric acid electrolyte increased by 45.5% at 700 V, 40.0% at 800 V, and 66.7% at 900 V.
