中文摘要 | 本研究以99.46%之鋁為陽極,鉛為陰極,0.5 M之草酸為電解液對鋁作陽極處理,探討電壓、陽極處理時間、溫度及鋁基材厚度等對所生成氧化鋁皮膜厚度及奈米孔洞大小的影響。以掃描式電子顯微鏡(SEM)觀察實驗結果。實驗所得最大皮膜厚度為28.2μm,將近Whatman公司商業化氧化鋁皮膜的一半。最大孔洞密度為1.2* 1010個孔洞/cm2,孔洞大小為30~60 nm。實驗結果發現陽極處理溫度愈高、時間愈久,皮膜厚度愈厚。電壓愈大時,孔洞愈大,而密度愈小。陽極處理溫度愈低,孔洞密度愈大。鋁基材厚度愈小時,孔洞直徑和孔洞密度都會愈小。孔洞之深度需以解析度更好的場發式電子顯微鏡來觀察,鋁基材之平坦度和純度影響甚大,純度應再提高才能得到更好之結果。 |
英文摘要 | The 99.46% aluminum sheet was anodized with 0.5 M oxalic electrolyte. We investigated the effects of voltages, anodic periods of time, temperature and the aluminum substrate thickness on the produced anodic porous alumina membranes. The anodic porous alumina membranes were characterized by scanning electron microscope. The maximum produced anodic alumina membrane thickness reaches 28.2μm, which is near half of the Whatman's product. The maximum nanopore's density is 1.2*1010 /㎝2 and the diameter ranges from 30 to 60 nm. We find that the anodic alumina layer thickness increases with increasing anodic treatment temperature and periods of time. When the applied voltages increases, the diameter of the nanopores increases but the density decreases. The nanopore's density increases with decreasing anodic treatment temperature. The diameter and density of the nanopores decrease with decreasing the aluminum substrate thickness. The depth of the nanopore needs to be investigated by field emission scanning electron microscope. The roughness and purity of the aluminum affect the properties of the anodic porous alumina membranes significantly. |
