The linear and nonlinear rheological behaviors of semidilute aqueous solutions of the amphiphile triblock polymer Pluronics P103 in water are reported here. For C(surf) < or = 20 wt%, micelles are spherical at temperatures lower than ca. 27 degrees C and grow with increasing temperature to form long polymer-like micelles. These polymer-like micelles exhibit strong viscoelasticity and a shear-banding region that shrinks as the cloud point is approached. Master time-temperature-concentration… Expand
Shear-induced structural and thermodynamic phase transitions in micellar systems
TLDR
A methodology to compute and classify shear-induced structural and phase transitions in surfactant/water mixtures from rheological measurements is presented and is able to identify the instability regions where the wormlike micelles are broken, producing the typical shear banding behavior. Expand
A master dynamic flow diagram for the shear thickening transition in micellar solutions.
TLDR
A relationship between the shear thickening intensity and the differences in the hydrophobicity of counterions according to the Hofmeister-like anion series is reported, which leads to a master flow diagram that is built using several cetyltrimethylammonium-type surfactants with different counterions, according to a Hofmeisters-like series.

TLDR
The results show that the thermogelation is due to the clustering of nanoparticles into a fractal network rather than a close-packed F108 micelles, in agreement with the recent findings in Pluronic F127-laponite systems. Expand
