中文摘要
本研究的总体目标是更好地了解几种独特的自组装体系在稀、半稀和浓溶液状态下的物理和化学性质。阴离子和阳离子表面活性剂的混合物将作为温度、溶剂盐度和两种表面活性剂的相对浓度的函数进行研究。还将研究表面活性剂-酒精混合物,以了解结构异构体对物理化学性质的影响。这些研究目标将通过各种光学和物理化学技术的应用来实现,例如光散射、粘度和表面张力技术对胶体和胶束系统的应用。表面活性剂和表面活性剂的混合物广泛用于工业加工、生物和药物制剂以及药物输送系统。学习这些系统中自组织的物理和化学以及对其性质的操纵的学生,将获得相当重要的技术领域的技能和知识。* * *
英文摘要
9727708 Fisch The overall goal of this research is to obtain a better understanding of the physical and chemical properties of several unique self-assembled systems in the dilute, semidilute, and concentrated solution regime. Mixtures of both anionic and cationic surfactants will be studied as a function of temperature, solvent salinity, and relative concentration of the two surfactants. Surfactant-alcohol mixtures will also be studied to understand the effects of structural isomers on the physico-chemical properties. These research goals will be achieved by application of a wide variety of optical and physical chemical techniques such as light scattering, viscosity and surface tension techniques to colloidal and micellar systems. %%% Surfactants and mixtures of surfactants are used extensively in industrial processing, biological and pharmaceutical preparations, and drug delivery systems. Students studying the physics and chemistry of self-organization in these systems, and the manipulation of their properties, will acquire skills and knowledge in an area of considerable technological importance. ***
