Kinetics of the sphere-to-rod like micelle transition in a pluronic triblock copolymer
(2012)
The kinetics of the sphere-to-rod transition was studied in aqueous micelle solutions of triblock copolymer poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) pluronic P103 (PEO17PPO 60PEO17). This transition ...
Temporal evolution of the size distribution during exchange kinetics of pluronic P103 at low temperatures
(2009)
The micellar dynamics of many (PEO-PPO-PEO) triblock copolymers have been extensively investigated throughout the past decade using ultrasonic relaxation or temperature jump experiments. These methods primarily use the ...
Rheology of the Pluronic P103/water system in a semidilute regime: Evidence of nonequilibrium critical behavior
(2009)
The linear and nonlinear rheological behaviors of semidilute aqueous solutions of the amphiphile triblock polymer Pluronics P103 in water are reported here. For Csurf ≤ 20 wt%, micelles are spherical at temperatures lower ...

Flow regimes of dilute surfactant solutions
(2001)
The shear-thickening of dilute surfactant solutions is investigated using water/cethyltrimethylammonium tosylate (CTAT) systems. We show that shear induced structures (SIS) are obtained in Couette and parallel-plate flows ...
Phase behavior of the Pluronic P103/water system in the dilute and semi-dilute regimes
(2009)
The detailed temperature-composition phase diagram of the P103/water system in the dilute and semidilute regions is reported here using density and ultrasound velocity measurements, differential scanning calorimetry (DSC), ...
On the shear thickening behavior of micellar aqueous solutions of cetyltrimethylammonium fluorobenzoates: Effect of the fluor position
(2013)
The shear thickening behavior of micellar solutions made with homologous cetyltrimethylammonium (CTA) fluorobenzoate (FB) surfactants, in which the fluor is located in the 2-(CTA2FB), 3-(CTA3FB) or 4-position (CTA4FB) of ...
