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

Abstract

Stimulus-responsive surfactant wormlike micelles have been widely investigated in the past decade. In this article, we report light and CO2/N2 dual stimuli-responsive wormlike micelles using a zwitterionic surfactant (SDAP) and an azobenzene surfactant (C4AzoC6N). In contrast to traditional amine-containing wormlike micelles, a fast and reversible CO2-triggered thinning behavior was observed. The system can also be reversibly switched by UV irradiation. The dual stimuli-responsive wormlike micelles (C4AzoC6N–SDAP) may have applications in the development of functional materials for microfluidics and analytical chemistry.
