Light and CO2/N2 dual stimuli-responsive wormlike micelles based on a zwitterionic surfactant and an azobenzene surfactant

Stimulus-responsive surfactant wormlike micelles have been widely investigated in the past decade. In this article, we report light and CO 2 /N 2 dual stimuli-responsive wormlike micelles using a zwitterionic surfactant (SDAP) and an azobenzene surfactant (C 4 AzoC 6 N).

Summary:Stimulus-responsive surfactant wormlike micelles have been widely investigated in the past decade. In this article, we report light and CO 2 /N 2 dual stimuli-responsive wormlike micelles using a zwitterionic surfactant (SDAP) and an azobenzene surfactant (C 4 AzoC 6 N). In contrast to traditional amine-containing wormlike micelles, a fast and reversible CO 2 -triggered thinning behavior was observed. The system can also be reversibly switched by UV irradiation. The dual stimuli-responsive wormlike micelles (C 4 AzoC 6 N-SDAP) may have applications in the development of functional materials for microfluidics and analytical chemistry. Light and CO 2 /N 2 dual stimuli-responsive wormlike micelles (WLMs) were prepared with a zwitterionic surfactant and an azobenzene surfactant. In contrast to traditional CO 2 responsive WLMs, a fast and reversible CO 2 -triggered thinning behavior was observed.
