摘要：
The growth and structure of anionic micelles of sodium dodecyl trioxyethylene sulfate (AES) in the presence of multivalent counterion Al3+ were investigated by means of dynamic rheological methods. It has been obtained by themeasurements of shear viscosity, complex viscosity anddynamic moduli, as well as the application of Cox-Merz rule and Cole-Cole plot that wormlike micelle and networkstructure could be formed in AES/AlCl3 aqueous solutions. The structure was of a character of nonlinear viscoelasticfluid and departure from the simple Maxwell model. Thetechnique of freeze-fracture transmission electronmicroscopy (FF-TEM) was also used to confirm theformation of this interesting structure.
