摘要：

A hard-mild anodization combined method (HA-MA) for rapidly fabricating highly ordered porous anodic alumina (PAA) membranes is presented in this paper. Firstly, by using hard-anodization (HA), the ordered pit arrays on aluminum surface were rapidly prepared and then, by using mild anodization (MA), ordered PAA membranes were fabricated on the ordered pit arrays aluminum surface. The effect of HA parameters, such as anodization voltage and duration, on the order degree of as-fabricated PAA membranes were investigated. The results showed that the optimum HA voltage and duration in 0.3 mol/L sulfuric acid at -1.5 degrees C were 80 V and 10 min, respectively. The order degree and mechanical stability of as-fabricated PAA membranes were similar to that of PAA membranes fabricated by two-step MA method, but its total process duration was within 4.5 h, which cost only about 1/4 time as that of by two-step MA method, The HA-MA method greatly improved the fabrication efficiency of ordered PAA.
