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.

Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...
