چکیده

The shear-induced microstructure of a shear-induced phase separating (SIPS) wormlike micellar solution is measured by combining small-angle neutron scattering with a shear cell capable of gap-resolved measurement in the 1-2 (velocity-velocity gradient) plane. Quantitative results show evidence for shear-induced microphase separation accompanied by shear banding. The results suggest both concentration fluctuations and gradients in segmental alignment occurring during SIPS.

Dynamic response of block copolymer wormlike micelles to shear flow

The flow behavior of giant wormlike micelles consisting of Pb-Peo block copolymers in the vicinity of the isotropic-nematic phase transition concentration is studied. We explain the appearance of shear banding close to this transition by critical slowing down of the rotational diffusion. This is evidenced by a combination of Fourier transform rheology, time-resolved Small Angle Neutron Scatteri...

Investigating the Structural Mechanisms of Shear Banding Using Spatially-resolved Flow-SANS

Shear banding is a flow-induced phenomenon observed in a wide variety of materials, including highly entangled polymers, self-assembled surfactants, colloidal suspensions, and pastes. Its rheological and macroscopic signatures have been well-studied for over a decade, yet surprisingly little is known about the underlying microstructural mechanism(s) that give rise to shear banding in soft matte...

Shear-induced phase separation in solutions of wormlike micelles.

Polymer solutions in the vicinity of the theta-point are known to undergo shear-induced turbidity or phase separation. The present study shows that a similar phenomenon also occurs for certain wormlike micellar solutions. Wormlike micelles are the self-assembled counterparts of polymers and are characterized by their ability to reversibly break and recombine. In the system of interest, the mice...

SHEAR BANDING IN WORMLIKE MICELLAR SOLUTIONS Summer School on Neutron Scattering and Reflectometry

Wormlike micelles are an important class of surfactant micellar architectures that find use in applications ranging from consumer products to energy and nanomaterials. Many wormlike micellar systems exhibit a flow instability known as shear banding, characterized by an inhomogeneous flow field. Although many of the proposed mechanisms and theories for shear banding revolve around fluid microstr...

Influence of nanoparticle addition on the properties of wormlike micellar solutions.

The addition of positively charged, 30 nm diameter silica nanoparticles to cationic wormlike micellar solutions of cetyltrimethylammonium bromide and sodium nitrate is studied using a combination of rheology, small angle neutron scattering, dynamic light scattering, and cryo-transmission electron microscopy. The mixtures are single phase up to particle volume fractions of 1%. The addition of li...
