摘要
表面活性剂在溶液中可通过自组装形成胶束、囊泡、液晶等多种有序结构。这些有序自组装结构在催化化学、材料制备、生物医药等领域有着重要而广泛的用途。控制和改变表面活性剂在溶液中的聚集方式对表面活性剂的应用具有重要的意义。近年来,通过对外界环境的调控来改变表面活性剂的物理化学性能如表面张力、聚集形式等研究已成为表面活性剂研究的一个新方向。本文以外界环境变化对表面活性剂在溶液中的聚集方式的影响为基础,介绍了可对环境刺激产生响应的表面活性剂的种类、结构、性能及研究进展,并总结了它们的结构与环境刺激响应性能之间的关系。
Surfactants can be self-assembled into organized structures such as micelles, vesicles, liquid-crystals in the solution. These organized structures have been found broad applications ranging for catalysis, preparation of novel materials to biopharmaceutics. Controlling and changing the surfactant aggregation plays an important role for their applications. Recently, tuning the physicochemical properties of surfactants through represents a new direction in surfactant science. The recent progress of six types of surfactants, i.e., pH-, electrolyte-, organic molecule-, temperature-, photo-, and are reviewed, and the relationship between their responsive properties and molecular regulating environmental condition environmentally stimuli-responsive redox-stimuli responsive surfactants structures is discussed. The future trends of these surfactants are outlooked in this review.
