在一次阳极氧化法制备多孔氧化铝(anodized aluminum oxide,AAO)的基础上,进行了二次、三次、四次氧化制备AAO,并对多次氧化制备多孔AAO的电流变化曲线和模板表面的形貌特点等进行了比较分析.二次、三次、四次氧化制备的AAO纳米孔孔径依次增大、孔间距减小,而模板表面的纳米孔有序性分布没有明显变化.控制一次氧化AAO模板的除膜时间,～10 min即可得到孔径规则、高度有序的AAO膜.最后,利用所制备的不同孔深和孔径的AAO为模板,通过热纳米压印复制技术制备了长度和直径等性质可控的PMMA纳米柱阵列.On the basis of the first oxide prepared anodized aluminum oxide template (AAO), the second, third and fourth oxidation preparation are implemented in turn. Then, the surface morphology and current curve changes of the AAO template with multiple oxidation preparation were compared and analyzed systemically. The apertures of nanopore made by the second, third and forth oxidation increase in order, the intervals between neighboring apertures reduce. However, the scale of ordered distribution of nanopores on the whole template surface does not change significantly. Then, carefully controlling the working conditions for the membrane-removed of the one-step oxidation AAO, the nanoporous with regular apertures and highly ordered was obtained after getting rid of the top oxidation layer about 10 minutes. Finally, based on those prepared AAO templates, integrated with the thermal nanoimprint lithography, we achieved the PMMA nano-pillar arrays with controllable lengths and diameters.
