| 摘 要： | 本文使用磷酸和草酸的混合溶液为电解液,在90V电压下,控制电解液温度在5～10℃制备了平均孔径高达200nm,开孔密度为1.7×109pores/cm2的多孔阳极氧化铝（AAO）膜。与使用单一酸为电解质相比,使用混合酸制备大孔径氧化铝膜所需的电压较低,电流密度较小,对氧化温度的要求也不苛刻。

| Abstract: | Anodic aluminum oxide （AAO） membranes, with as high as 200 nm of mean pore diameter and about 1.7×109 pores/cm2 of pore density, are successfully prepared in mixed electrolyte （H3PO4 /H2C2O4） at temperature of 5~10℃ under 90 V. Large pore diameter AAO membranes have been prepared at lower anodizing voltage, current density and milder temperature by using the mixed acid electrolyte compared with using the sole acid electrolyte. |
