近年来,利用超分子作用力调节体系流变行为备受人们关注,已在多领域中展现出广泛的应用前景。而环糊精包合作用是一类重要的超分子作用力,向缔合聚合物水溶液中加入环糊精,将拆散缔合结构,引起粘度和粘弹性急剧下降;竞争客体或酶的加入又会诱导分子间发生新的组装行为,使体系流变性得到恢复。本文综述了基于环糊精包合作用的分子组装与流变调节在理论及应用方面的研究现状,重点介绍了环糊精对不同缔合聚合物溶液的流变影响规律和外加物质对体系流变恢复的调节。
In recent years, the use of supramolecular force to regulate the rheological behavior of the system has drawn much attention and has shown broad application prospects in many fields. Cyclodextrin inclusion is an important type of supramolecular force. Adding cyclodextrin to the aqueous solution of associative polymer will break up the association structure and cause a drastic drop in viscosity and viscoelasticity. The addition of competing objects or enzymes Will induce a new assembly behavior between molecules, so that the system rheological recovery. This review summarizes the theoretical and application research on molecular assembly and rheology regulation based on inclusion of cyclodextrins, and focuses on the influence of cyclodextrin on the rheology of different associative polymer solutions and the effect of added substances on the flow of system Variable recovery regulation.
