主要研究領域 高分子物理 高分子產物在人類的生活中已成為不可或缺的物質，但由於其結構遠較一般簡單分子複雜，我們對它功能的瞭解及研發的工作，常僅止於經驗式的進行。本研究小組即是利用電腦模擬與統計熱力學的方式，嘗試由微觀層次來研究高分子系統宏觀特性，希望能藉此更進一步瞭解高分子的熱力性質與動態行為。 含帶電界面之熱力平衡系統 靜電作用是隨距離一次方遞減的長距離作用，即r-1；該特性使得有關含離子系統的研究，如生物與奈米系統，變得相當棘手。與高分子系統類似，這種系統常需考慮複雜的多體作用。我們著重於以平均場理論初步地瞭解系統的熱力學性質；再以分子模擬的方法探討離子擾動性與相關性對這類系統的影響。 最新研究計畫 [ol]Monte Carlo studies of conformational segregation of a diblock star copolymer以蒙地卡羅法研究雙段星狀共聚高分子之型態相分離(1/3) Sheng, Yu-Jane, sponsored by National Science Council #NSC94-2214-E-002-020 8/1/2005-7/31/2006.
