The Rheology of Worm-like Micellar Fluids

This article reviews what has been published on the rheology of worm-like micellar fluids (WLMFs). It is written primarily for those interested in continuum (non-Newtonian fluid) mechanics: it covers the bulk rheological behaviour of typical WLMFs and rheological equations of state (REoS) that reflect this bulk behaviour; it also covers molecular dynamics and Brownian dynamics models that aim t...

Inhomogeneous structure formation and shear-thickening in worm-like micellar solutions

– The time evolution of flow-induced structures in low-concentration worm-like micellar solutions is studied using direct visualization and rheological methods. The visualization measurements show growth of a new viscous shear-induced phase (SIP) starting on the inner wall of a Couette shear cell at a time t1 after the commencement of shear flow. The SIP continues to grow across the shear cell ...

Anomalous diffusion and power-law relaxation of the time averaged mean squared displacement in worm-like micellar solutions

We report the results of single tracer particle tracking by optical tweezers and video microscopy in micellar solutions. From careful analysis in terms of different stochastic models, we show that the polystyrene tracer beads of size 0.52–2.5μm after short-time normal diffusion turn over to perform anomalous diffusion of the form 〈r2(t)〉 ' t with α ≈ 0.3. This free anomalous diffusion is ergodi...

Rod like micellar structures in perfluorinated ionomer solutions

2014 A hexagonal packing of rod like structures is proposed in solutions and gels of a perfluorinated ionomer. The diameter of the rods has been obtained by two different approaches either geometrical from shifts of the interference peak versus concentrations in small angle scattering experiments or direct from analysis of the structure factor in diluted solutions. Consistent results give value...

MRI Experiments as a Tool to Study Asymptotic-Shear Flow Behaviour of a Worm-Like Reverse Micellar Phase

This paper deals with a Magnetic Resonance micro-Imaging (MRI) analysis of asymptotic kinematics which is a condition adopted in some rheological characterisations. Asymptotic kinematics (for example the slow shearing ) aim is to evaluate material properties at “equilibrium”, avoiding structural changes induced by external stimuli. Measured material functions in these mechanical conditions deal...
