電致色變材料與元件

  電致色變現象是指材料伴隨電子轉移時導致之可逆顏色變化。經由人們的輸入訊號,電致色變元件能連續地改變透明度,可用於變色太陽眼鏡、天窗、遮陽板、後視鏡等商品上。因為輸入訊號的形式是直流電壓或電流,這些元件本質上可由使用者控制。目前我們正進行普魯士藍電致色變薄膜及其類似物的製備與鑑定,期對進出的離子在與電致色變材料的交互作用上有更進一步的瞭解。本研究涉及應用固態物理學、材料科學、高分子化學、電化學/電化學工程的原理,以改進電致色變材料與元件的長期穩定性。而其他與電致色變技術相關的材料,如導電高分子、透明電子與離子導體,也一併在研究之列。

電化學反應工程

電化學反應工程是將輸送現象、電化學平衡、電極動力學和材料科學的原理應用於化學程序中涉及電荷轉移反應的學門。最近幾年,電化學現象的重要性在許多工業製程裡逐受重視。經由進一步對電極材料的了解與設計,我們對發展嶄新的電化學反應器持有高度的興趣。例如原先在半導體工業使用的二氧化鈦鍍層透明電極,在本實驗室將其修飾改質充作光電化學反應器內之光觸媒與電極材料而用於水質的純化。其它的電極材料,例如聚苯胺和太菁也一併被研究;作為電化學式與半導體式氣體感測器內之感測電極而用於空氣污染之監測
