本研究项目的目的是通过对胶束、膜和囊泡等各种分子组装体在溶液中的状态变化的追踪，获得一些新的有用的信息，并阐明它们的功能。(1)用小体系热力学方法分析了聚氧乙烯烷基醚和N-烷酰基-N-甲基葡糖胺（MEGA-n）的光散射数据。(2)对不同类型表面活性剂的各种混合体系进行了研究：（a）全氟辛酸钠（SPFO）与十二烷基硫酸钠（SDS）和与癸基硫酸钠（SDeS），（B）SDS与牛磺脱氧胆酸钠（NaTDC），（c）SPEO与MEGA-9，以及（d）MEGA-9与MEGA-10。(3)用ESR自旋共振和荧光标记技术研究了几种胆盐胶束及胆盐与卵磷脂混合胶束的内部结构。(4)为了阐明胆盐在脂质消化中的作用，研究了胆盐对甘油三酯、甘油二酯和甘油单酯的增溶作用， ...更多信息 对牛磺熊去氧胆酸钠（NaTUDC）和牛磺鹅去氧胆酸钠（NaTCDC）在胆盐胶束中的作用进行了比较。(5)对全氟癸酸钠（SPFDe）在水中的溶解进行了压力和温度研究，确定了该体系的临界溶解温度（Krafft温度）和临界溶解压力（Tanaka压力）。(6)通过研究气泡破裂时顶部射流液滴中颗粒的富集因子，建立了气液界面科学的一种新方法。(7)本文提出了一种热力学分析方法，对同系物烷醇从水中向氟碳化合物和烃类表面活性剂胶束中转移的数据进行了分析。(8)研究了具有分散或分离电荷的非金属阳离子抗衡离子的阴离子表面活性剂是否会出现与常规表面活性剂大不相同的物理化学性质。本研究的发现是，溶解度、CMC、胶团化热和胶团温度范围（MTR）与传统阴离子表面活性剂有很大不同。少

The aim of this research project is to obtain some new and useful information on various molecular assemblies such as micelles, films and to vesicles and elucidate their functions by pursuing their state changes in solution. (1) The small system thermodynamics has been developed for analyzing the light scattering data obtained for polyoxyethylene alkyl ethers and N-alkanoyl-N-methylglucamines (MEGA-n). (2) Studies on various mixed systems of different types of surfactants were performed: (a) Sodium perfluorooctanoate(SPFO) with sodium dodecylsulfate(SDS) and with sodium decylsulfate(SDeS), (b) SDS with sodium taurodeoxycholate(NaTDC), (c) SPEO with MEGA-9, and (d) MEGA-9 with MEGA-10. (3) The interior structures of micelles of several bile salts and the mixed micelle of bile salts with lecithin were surveyed by means of ESR spin and fluorescence label techniques. (4) To elucidate the role of bile salts in lipid digestion, the solubilization of triglyceride, diglyceride and monoglycerid … More e by bile salt micelles was investigated and the results were compared between sodium taurochenodeoxycholate(NaTCDC) and sodium tauroursodeoxycholate(NaTUDC). (5) A pressure and temperature study was made on sodium perfluorodecanoate(SPFDe) in water and for this system the critical solution temperature (Krafft temperature) and the critical solution pressure(Tanaka Pressure) were determined. (6) A new approach for gas/liguid interface science was established by examining the enrichment factor of particles in top jet drops from bursting bubbles. (7) A method of thermodynamic analysis was proposed with respect to the data upon the transfer of homologus alkanols from water to fluorocarbon and hydrocarbon surfactant micelles. (8) Anionic surfactants with nonmetallic cationic counterions of diffused or separate electric charge were examined to see if the physico-chemical properties much different from those of conventional surfactants would appear. The finding from this study is that a solubility, CMC, a heat of micellization, and the micelle temperature range (MTR) are quite different from those of conventional anionic surfactants. Less
