摘要：以草酸溶液为电解质,采用两步电化学阳极氧化法制备了氧化铝有序多孔膜,研究了阳极氧化电压对多孔膜生长过程及形貌的影响．结果表明,电流密度、生长速率及孔径、孔间距随电压的升高而增大,而膨胀因子与电压呈线性关系．氧化铝膜的孔隙率保持在12％左右,与电压基本无关．
Two-step electrochemical anodizing approach was introduced to prepare the porous aluminum oxide （AAO） membrane in oxalic acid solution. The dependence of morphology and growth process of AAO membrane on applied voltage was studied. It is found that current density, growth rate, pore diameters and pore distances of AAO membrane increase with the anodizing voltage increasing and the volume expansion factor varies linearly with the anodizing voltage. The porosity keeps a constant of 12%, which is independent of the applied voltage.
