Wormlike Micelles of a C22-Tailed Zwitterionic Betaine Surfactant:  From Viscoelastic Solutions to Elastic Gels

Abstract: The 22-carbon-tailed zwitterionic surfactant erucyl dimethyl amidopropyl betaine (EDAB) forms highly viscoelastic fluids in water at low concentrations and without the need for salt or other additives. Here, semidilute aqueous solutions of EDAB are studied by using a combination of rheological techniques, small-angle neutron scattering (SANS) and cryo-transmission electron microscopy (cryo-TEM). EDAB samples show interesting rheology as a function of temperature. At low temperatures (approximately 25 degrees C… Show more

“…This is evidence that microemulsions were present in the solution. 5,7,8,30 Cryo-TEM revealed the existence of microemulsions along with short and thin cylindrical micelles in the surfactant solution with 3 wt% n-decane equilibrated at 60 C (Fig. 11).…”

“…Long-tail surfactants have been of interest of research due to their various applications as viscosifying agents. 5 Moreover, long-tail sulfobetaine surfactants have been reported to be a good candidate for especially high-temperature applications such as well stimulation. 33 Despite this interest, micellar changes of long-tail sulfobetaine surfactants induced by organic compounds have not been published.…”
