In order to design materials, finding out how self-assembly behavior is affected by the chemical structure of the substance, external environmental factors and external forces, and coming to understand the relationship between them. The relation between molecular structure and self-assembly properties can describe by packing parameter, but it exists some disadvantage, on the contrary, at continuum mechanics, the monolayer formed self-assembly behavior is considered a continuous flexible solid thin film, and it can describe by the elastic energy density. Through our experiment (SAXS and SANS), We think that we could use the spontaneous curvature and bending modulus to check the self-assembly structure, so when we know these parameters, we could develop the structure we wanted. en_US DC.subject 自組裝結構 zh_TW DC.subject 雙子型界面活性劑 zh_TW DC.subject 由下而上 zh_TW DC.subject 堆疊參數 zh_TW DC.subject 自由能 zh_TW DC.subject self-assembly structure en_US DC.subject gemini surfactant en_US DC.subject bottom-up en_US DC.subject packing parameter en_US DC.subject free energy en_US DC.title 開發預測雙子型界面活性劑之自組裝結構的方法 zh_TW dc.language.iso zh-TW zh-TW DC.title DEVELOPING THE METHOD OF PREDICTING THE SELF-ASSEMBLES STRUCTURE OF GEMINI SURFACTANTS en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
