From Wall Slip to Bulk Shear Banding in Entangled Polymer Solutions

This article reviews the past activities and emergent understanding of nonlinear rheology of entangled polymeric liquids, with the purpose of pointing out the remaining challenges. A key component of this subject concerns wall slip and shear strain localization, for example, shear banding. It is emphasized that wall slip and shear banding are not isolated phenomena and share the same conceptual origin. The concept of the extrapolation length...
