Abstract:The
viscoelasticity of wormlike micelles composed of ionic surfactants
typically shows an exponential decrease with increasing temperature,
which limits their application in relatively high-temperature (>90.0
°C) oilfields and the synthesis of functional materials as supramolecular
templates at high temperatures. In this work, a series of imidazolium
gemini surfactants, 1,9-(ethane-1,2-diyl)bis(3-alkyl-1H-imidazol-3-ium) bromide ([C
