兩相界面動力學與擴散行為分析

分子在表面吸附及與交互作用行為一直都是科學與工程上的重要研究課題，其應用也非常廣泛，由於尺寸效應影響下，不同分子或材料在界面的的特性通常與其結構或動力行為息息相關，而影響分子結構的原因相當多元，例如：在分子在固體表面的吸附分析研究上，我們發現分子在不同同分異構物結構、溫度、平面排列的基板表面皆會影響到分子的擴散能力與其結構方向性。高分子PMMA薄膜吸附於金屬不同平面方向之表面時、不同鍊長及溫度下，會影響其界面的表面自由能、分子結構方向性、密度與表面張力，結果指出在界面處會有高能密度區，其高分子結構會規則有序的吸附於表面；在電解質在水溶液下的自組裝行為分析研究上，我們發現不同的電荷密度下，PMAA 的結構會有所改變，而在COO基團中之氧原子附近的水與COO基團之排列特徵也會跟著改變。而水分子則是影響結構穩定與電解質動態行為的重要影響因素；在表面浸濕(surface wetting)行為的分析研究上，我們發現奈米水團簇內與團簇外擁有不同的分子擴散及氫鍵動態行為，而水團簇的溫度與尺寸會影響到奈米團簇內分子的動態行為，還會改變到兩奈米水團簇聚集時的成形速率，及當其吸附於表面時的擴散行為；最後，在分子在侷限空間內之行為研究上，發現不同大小的侷限空間、不同排列平面的基材結構、及環境溫度，皆是影響水分子吸附現象的重要參數，研究成果包括：(1)金奈米微粒於水溶液中的吸附現象分析(2)微導管傳輸現象分析(3)雙層奈米薄膜的吸附現象分析。
