SHEAR THICKENING OF AN AQUEOUS MICELLAR SOLUTION OF CETYLTRIMETHYLAMMONIUM BROMIDE AND SODIUM TOSYLATE

In this experimental study we give results concerning the shear thicke ning behavior exhibited by an aqueous cationic surfactant solution of CTAB in the presence of added NaTOS. We carefully investigate the rheo logical characteristics of this phenomenon corresponding to a shear in duced state (SIS), the reproductibility and also the transient regimes . Wie show that with steady experiments there exist no hysteresis effe ct. Finally we give the evolution of the shear thickening characterist ics against temperature.
