 研究計畫

本實驗室從事與膠體與界面科學、高分子物理、及生物物理等相關領域的基礎和應用研究。研究範疇包括系統處於非平衡狀態時,流動、擴散或動力學特性的探討;及系統達到平衡時,其熱力學特性的研究。

目前我們所研究的膠體系統主要是含有巨離子(macroion)的電解質溶液。巨離子是帶有許多電荷的奈米粒子,包括有一般的奈米粒子、長鏈的高分子(polyelectrolyte)、和界面活性劑所形成的微胞等等。其大小遠比溶劑分子大,但卻比微米(mm)來的小。瞭解這些系統的物理性質可作為工業應用(例如分離操作)的參考和基礎。我們也研究液滴在固體表面的潤濕行為,包含超疏水表面的潤濕及其原理探討,這些研究結果可應用於半導體製程中化學機械研磨後清洗操作的改進依據。

我們的研究方法是《理論分析》與《實驗觀察》並重。為瞭解現象的基本機制並提供預測的功能,我們是以統計力學的方法為基礎,從瞭解系統中《微觀》的粒子間相互作用特性著手,再進一步去推導及觀察系統所呈現的《宏觀》性質。利用電腦快速運算的功能,我們可以用分子模擬(molecular simulation)的方法來進行所謂的《電腦實驗》,找出系統的宏觀性質。同時,我們也掌握所建構的理論模型的精神,設計簡單而便宜的實驗,驗證我們的理論或作為修正模型的依據。
