摘要
在相同的工艺条件 ,分别用磷酸、磷酸与草酸混合溶液为电解液制备了多孔铝阳极氧化膜(AAO) ;用TEM观察了膜的形貌 ,表明膜的表面有排列较规则、具有一定准周期性的微孔 ,微孔的孔径大约为 75nm ;对于在磷酸与草酸混合酸中氧化的工艺 ,氧化膜较厚 ,通过扫描电镜观察 ,其膜厚在 5 0 μm左右 .X射线衍射分析表明 ,在低于 60 0℃热处理的条件下铝箔表面的阳极氧化膜基本上是以无定形态存在 ,经 90 0℃热处理无定形氧化铝开始结晶出γ -Al2 O3。
In the same process conditions, porous Anodic Aluminum Oxide(AAO) films have been prepared in phosphoric acid, mixture of phosphoric acid and oxalic acid separately. TEM observation of the aluminum film indicates that pores arrange in a quasi-periodic way. In the film, the nanopore is about 75nm. For the sample anodized in mixed acids, the film is relatively thick. Under observation with SEM, the thickness of the film is about 50μm. X-ray Diffraction result indicates that the oxide film on the surface of aluminum is amorphous if annealing temperature is lower than 600℃. The amorphous aluminum begins to transform to γ-Al 2O 3 when they are annealed at temperature of 900℃. The amorphous film fabricated by this technology is comparatively steady.
