Worm-like micelles entangle and form networks like polymeric fluids. In the present study surfactant solution systems of CTAB/NaSal were used to examine the flow property with a strain-controlled parallel-plate rheometer and to carry out birefringence measurements of surfactant solutions. At relatively low salt concentrations, transient birefringence after step changes in shear rate exhibited large overshoot at high shear rates and the convergent value of birefringence is relatively small. On the other hand, at relatively high salt concentrations, transient birefringence after step changes in shear rate exhibited small overshoot at high shear rates and the convergent value of birefringence is relatively large. Thus, the occurrence of the birefringence overshoot in the step-rate response is related to the salt concentration.
