Abstract:

Smart wormlike micelles (SWLMs) possess reversible stimulus-responsive assembly characteristics, which have become a research hotspot in colloid chemistry, oil and gas production, and biomedical fields. Based on the previous research series on wormlike micelles, this paper focuses on the intelligent design mechanism, construction strategies, classification systems and practical applications of SWLMs. The intelligent response of micelles relies on reversible non-covalent weak interactions and adjustable dynamic equilibrium, and external stimuli can change the critical packing parameter to realize reversible morphology transformation between spherical and wormlike micelles, further achieving sol-gel transition and rheological regulation. There are two mainstream construction approaches: Functional modification of surfactant molecules and regulation by the responsive hydrotropes. This paper systematically summarizes six typical stimulus-responsive systems, including temperature, pH, light, redox, hydrocarbon, and multi-coupled response systems, and clarifies their microstructural evolution and macroscopic rheological response mechanisms. Among them, hydrocarbon-responsive micelles have achieved large-scale commercial application in oilfield clean fracturing fluid, while pH, photo and redox-responsive systems show great potential in drug delivery, microfluidic control and green cleaning fields. At present, single-stimulus systems have limited application scenarios, and multi-stimulus coupled wormlike micelles developed via dynamic covalent bonds are the mainstream research direction. This review paper compares the advantages and limitations of different construction paths, analyzes the existing technical bottlenecks such as poor long-term stability of surfactant-hydrotrope systems and incomplete response reversibility of partial photo-responsive systems, and provides theoretical reference for the targeted molecular design and industrial application of high-performance SWLMs materials.

Key words: wormlike micelles, self-assembly, stimuli-responsive, sol-gel transition, rheology modifier, surfactant
