摘要
以鋁疊層法可製作具雙向成長之奈米孔洞陣列之陽極氧化鋁膜，本研究主要目的乃是探討此雙向成長奈米孔洞之成長機制。研究中先設計二種不同實驗，驗證此雙向成長之奈米孔洞陣列並非因電解液滲入夾具內而使漏液在純鋁表面的刻痕中反應之結果。實驗證實此現象並非漏液所造成。吾等進而將鋁疊層試片等效為間距極小之電容，當進行鋁疊層實驗時，電容將產生與陽極處理電壓反向之感應電壓，此感應電壓使作用於鋁試片之電場減小，而氧化鋁層厚度增加，氧離子在電場作用下會穿透氧化鋁層與未氧化之純鋁反應，細胞底部氧化層之Al-O鍵較容易極化產生焦耳熱並將其溶解，而在細胞底部產生額外的孔洞陣列，本研究進一步比較單層鋁試片/疊層鋁試片之管道長度以及利用光阻襯墊實驗證明此假設之正確性；並以控制鋁疊層氧化時間之實驗，成功製作出具有奈米膠囊陣列結構之陽極氧化鋁膜。此一特殊結構並未見諸於已發表之相關文獻中。

The foils laminate approach can be implemented to grow bi-directional porous pattern from both the top and bottom surfaces of an aluminum foil. It was intuitively inferred that leakage of the etchant between the foils may a feasible cause to have the upward pores grow in the notches of the unpolished surface. The leakage blocking and triple layers laminate experiments were conducted to verify this hypothesis. Experimental results disprove this leakage hypothesis. It is further inferred that applied voltage is diluted by the aluminum foils induced capacitor. The voltage reducing effect suppresses the dissolution more than oxidation such that an additional porous array that grows down from the cell base is formed. This voltage reducing mechanism has been verified by the pore height comparison and washer insertion experiments. Moreover, the laminate foils anodization was implemented to grow a nano-capsule array inside an alumina foil. This special structure of anodic aluminum oxide is novel.
