Dynamic and steady-shear rheological measurements of the AOT/water lamellar liquid crystalline phase are reported as a function of surfactant concentration. Dynamical measurements indicate that the AOT/water lamellar phase behaves as a weak gel; i.e., both the elastic and the loss moduli, \(G^{\prim

The rheological behavior of AOT/water liquid crystalline phases containing \(\mathrm{NaCl}\) or decane is examined here. Strong effects are noted on the elastic and loss moduli as well as on the complex and dynamic viscosities, even at low salt or decane content. Lamellar phases behave as weak gels;
