Rheological properties of wormlike micelles formed in the sodium oleate/trisodium phosphate aqueous solution

Aqueous solution of anionic surfactant, sodium oleate (NaOA), was studied by means of steady-state shear rheology and dynamic oscillatory technique. The system of NaOA/Na3PO4 showed high viscosity, strong viscoelasticity and good ability of countering Ca2+, Mg2+. The Maxwell model and Cole–Cole plot were applied to study the dynamic viscoelasticity of wormlike micelles. The microstructures of the wormlike micelles were characterized by FF-TEM.
