On the shear banding flow of elongated micellar solutions
Abstract Under steady shear flow, elongated micellar solutions show shear stress saturation above a critical shear rate due to the formation of shear bands that result in non-homogeneous flow. LongExpand
Phase behavior of the Pluronic P103/water system in the dilute and semi-dilute regimes.
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, differentialExpand
Dynamics of worm-like micelles: the Cox–Merz rule
Abstract The viscoelastic behaviour of worm-like micelles in small-amplitude oscillatory, steady simple shear and uniaxial extensional flows are analyzed with a model that couples the Oldroyd-BExpand
Rheology of Cetyltrimethylammonium Tosylate-Water System. 1. Relation to Phase Behavior
The partial phase behavior of CTAT/water is investigated here as a function of temperature by WAXS, DSC, polarizing microscopy, conductometry, 1 H-NMR, and FTIR spectroscopy. Oscillatory strain andExpand
Rheological behavior in the didodecyldimethylammonium bromide/water system
Abstract The phase behavior in the dilute region of the didodecyldimethylammonium bromide (DDAB)/water system is studied with a battery of techniques. The critical vesicle concentration (cvc),Expand
Irreversible Thermodynamics Approach and Modeling of Shear-Banding Flow of Wormlike Micelles
The flow in a pipe of wormlike micellar solutions is examined using a simple model that consists of the codeformational Maxwell constitutive equation and a kinetic equation that accounts for theExpand
Rheology of Lyotropic Liquid Crystals of Aerosol OT: II. High Concentration Regime
Abstract The rheological behavior of AOT/water dispersions over the whole two-phase concentration range (1.4 to 18.5 ± 1 wt% AOT at 25°C) is reported here. At a concentration around 8 wt% AOT, theExpand
On the wall slip of polymer blends
The slip flow of the polypropylene (PP)/poly[ethylene-co-(vinyl acetate)] (EVA) system was studied in a capillary rheometer for shear rates of 40–1000 s−1 at four temperatures. Three dies made ofExpand
Shear-banded flow and transient rheology of cationic wormlike micellar solutions
Linear oscillatory as well as transient and steady shear measurements for micellar solutions of dodecyltrimethylammonium bromide (DTAB) and sodium salicylate (NaSal) as a function of theExpand
