Abstract

A CO₂-switchable wormlike micellar system was fabricated using N-erucamidopropyl-N,N-dimethylamine without any hydrotropes. Its viscoelasticity varies by five orders of magnitude when cyclically bubbling CO₂ and air at ambient temperature and pressure without the need for heating, reflecting changes in aggregate morphology from entangled worms to spherical micelles.
