介面分子會因為其雙親性分子間的性質不同,而會有自組裝和相分離的特性,學者們利用此特性來產生不一樣結構,但由於鮮少有文獻描述介面分子內親水端和疏水端比例對平衡相態產生的影響。因此本研究利用耗散粒子動力學來模擬介面分子在溶劑下的平衡相態,且介面分子的親水端帶有靜電力場並利用Ewald summation來表達其靜電作用力,以探討介面分子內的親水端和疏水端比例以及介面分子和溶劑比例對系統平衡相態的影響,再藉由剖面結構圖來討論形成的特徵結構。
從模擬結果可以發現介面分子在溶劑不同比例中會產生X-shape、彎曲層板狀、網狀等特殊結構;而在介面分子中親水端和疏水端的不同比例也會形成不一樣結構的產生,如由微胞變球形結構、由彎曲層板變圓柱狀結構,因此可以知道在介面分子中,不只有溶劑比例會改變結構,且在介面分子內的分子比例也會造成影響,這對分子設計上和結構學有重大的影響,而所得到的新結構對於光電、醫藥、生物產業有很大的影響。
