中孔徑奈米材料的製備與應用
中孔徑奈米材料 (mesoporous materials) 具有大表面積，規則結構，均勻孔徑等優點，在基礎研究及實際應用上都受到相當重視。本研究室的研究著重在於此材料的合成與應用 ( 光電，能源及生醫方面 ) 。 合成製備上，我們將結合 Bottom-up 手法中的界面活性劑的自組裝特性 (Self-assebmly) 與 Top-down 手法中的半導體蝕刻技術 (Lithography) 來製作先端功能性的奈米孔徑材料。此製備方法包含了化學的合成及工學的製造。在基礎研究上，我們將會研究不同合成條件下對奈米結構的相轉移，不同孔狀結構的合成及構造解析，材料的功能化等相關題目。 在實際應用上，目前我們的材料應用著重於以下三部份： • 光電：色素增感太陽電池 • 能源：綠色能源，燃料電池 • 生醫：藥物與基因的傳遞與釋放　 藉由基礎與應用的研究，我們期待除了能發展出新的材料之外，更希望這些研究對人類健康與環境永續有所貢獻。
