基于动态亚胺键的智能表面活性剂蠕虫胶束OA

The molecular structure of surfactants determines the morphology of their self-assembled aggregates.Traditional wormlike micelles(WLMs)exhibit poor spontaneous recovery after structural disruption.However,if a dynamic covalent bond,e.g.,the imine bond,was introduced into the surfactant molecules,it could endow the micellar system with responsiveness to surrounding conditions(such as temperature and pH),and also endow it with self-adaptive capability,thereby enabling the construction of smart WLMs.In this review,the classification and fundamental properties of surfactants were introduced.Then the research progress in surfactant-based smart WLMs constructed via dynamic imine bonds was reviewed,focusing on their fabrication approaches and response mechanisms.Finally,some suggestions for the development of such systems were proposed.
