中文摘要: 表面活性剂在溶液中可自聚集形成多尺度多层次的聚集体,如胶束、囊泡、溶致液晶等,这些聚集体中有些结构可以形成表面活性剂凝胶。项目的主要研究内容包括:1)确认哪些表面活性剂聚集体(蠕虫状胶束、密集排列囊泡、溶致液晶和有序结晶等)可以实现表面活性剂的凝胶化;2)探明构成表面活性剂凝胶的多层次微观结构,确定溶剂被固定在表面活性剂凝胶微观结构上的作用力,如毛细作用和表面张力等;3)研究表面活性剂凝胶宏观上的类固体性质与微结构的构效关系,探究凝胶的成因、相转变以及形成机理;4)制备条件响应型表面活性剂凝胶,探索凝胶的润滑抗磨性能。 表面活性剂凝胶的研究将深化对表面活性剂聚集作用、聚集体结构和相转变的认识,所获得的制备简单、结构丰富、毒性小、成本低的表面活性剂凝胶将应用于药物工程、石油工程、传感器和润滑抗磨材料等领域。

英文摘要: Recently, new structures and applications of surfactant gels have been studied more and more. Surfanctants can self-assemble into various aggregations,like micelles, vesicles,and liquid crystals. i) To determine which aggregates from these structures can from gels. ii) To explore the fine microstructures of surfactant gels and determine the interaction for fixing solvents in the gel structures. iii) To study the macroproperties of surfactant gels. iv) To discuss the mechanism of gel formation and phase transition. v) To prepare stimulus-response surfactant gels and seek the possibility of surfactant gels as lubricants. Some good results would be presented in International Journals. Surfactant gels have many advantages, like simply prepared, rich structures, low toxicity and inexpensive, which can be applied in the field of medication engineering, petroleum engineering, materials synthesis, sensors, and lubricating materials.
