Viscoelastic response of diblock copolymers to oscillatory shear
Source abstract
Abstract
A mesoscopic model for diblock copolymers is combined with a simple rheological description of the viscoelastic contrast of its two phases. Under oscillatory shear the contrast generates secondary velocity fields and substantial deviations of volume-averaged flow parameters. The validity of our analytical findings is tested with three-dimensional numerical simulations. Furthermore, we consider the effect of advection by the generated flows on the stability of ordered lamellar states and propose a new criterion for the selection of orientations.

25. The instantaneous diffusion terms in equation (ns4) have been used to simplify the algebraic equations. In principle, the system can be solved without these terms, but we have performed this alternative calculation only for the base state. We did not find significant changes to the solution.
