1972年Fujishima和Honda發現二氧化鈦具有光觸媒效果，開啟了二氧化鈦的研究熱潮。二氧化鈦的奈米管陣列由於具有獨特的陣列結構及優異的性能，引起人們的關注。本研究利用陽極化製備二氧化鈦的奈米管陣列，藉由改變參數探討在各種反應條件對於奈米管的影響。結果顯示：隨著電壓的增加，奈米管管徑及其長度會隨之增加，而隨著溫度的降低，其長度及管徑有降低的趨勢。添加50%的聚乙二醇為電解質時,可得到較平整及略長的奈米管。
本文以二氧化鈦奈米管作為電致色變元件的接觸電極，並利用二氧化鈦奈米管的高表面積以提升電致色變元件的轉換效率，以PEDOT/PSS作為奈米管與ITO基板的連接層時，其著色態轉變時間可以降至6sec，為了增加PEDOT的導電度添加DMSO，可使元件的導電度增加，其著色態轉變時間降至3.8sec。
　　本文亦以二氧化鈦奈米管電鍍普魯士藍做為電致色變元件的工作電極，發現由於電致色變層的反應面積增加，整體元件的轉換效率有大幅的提升，褪色態轉變時間為0.6sec，而著色態轉變時間為5sec。

After Fujishima and Honda found that titanium dioxide could have photocatalysis property in 1972, many researchers showed great interests toward titanium dioxide. The successful synthesis of carbon nanotubes by Iijima in 1991 has stimulated the quest for the synthesis of nanotubular structures of other substances and chemical compounds, titania nanotubes as a new type of nano-materials with unique array structure and excellent properties, have attracted much attention around the world. In this thesis, we fabricated titania nanotube arrays by the anodization method and used different electrochemical parameters to characterize the growth behavior of titania nanotubes. Results show that the pore size and tube length will be increased by increasing the anodization voltage but decreasing the anodization temperature. With 50% PEG addition into the electrolyte, the surface of titania nanotubes becomes more smoothly.
In this thesis, titania nanotube was used as a counter electrode in a electrochromic device due to the high surface area characteristics. Titania nanotubes were transferred to ITO glass by using a PEDOT/PSS layer. The time period for transferring to colored state is 6sec. In order to improve the conductivity of the device, DMSO was added into PEDOT solution and resulted in a further reduced value of 3.8sec.
This thesis also used titania nanotubes with electroplated prussian blue as a working electrode. The increasing area of electrochromic layer improves the transition efficiency of the electrochromic device. The time period for transferring to the bleached and the colored state is 0.6sec and 5sec, respectively.
