Present Puzzles of Entangled Polymers
نویسنده
چکیده
Entangled polymeric fluids, including high molecular weight polymer melts, constitute a fundamental example of viscoelastic fluids. In spite of enormous advances in understanding the molecular origin of their rheology and microscopic dynamics, there are several pressing puzzles, some of them strongly linked, that offer current and pressing challenges. We review the current state of the field and nature of five current challenges.

Stress relaxation in entangled melts of unlinked ring polymers.
Stress relaxation in unlinked ring polymer melts poses an important challenge to our theoretical understanding of entangled polymer dynamics. Recent experiments on entangled unlinked ring melts show power-law stress relaxation with no hint of a rubbery plateau, usually the hallmark of entangled polymers. Here we present a theory for stress relaxation in rings analogous to the successful approac...
متن کاملNanoparticle Motion in Entangled Melts of Linear and Nonconcatenated Ring Polymers
The motion of nanoparticles (NPs) in entangled melts of linear polymers and nonconcatenated ring polymers are compared by large-scale molecular dynamics simulations. The comparison provides a paradigm for the effects of polymer architecture on the dynamical coupling between NPs and polymers in nanocomposites. Strongly suppressed motion of NPs with diameter d larger than the entanglement spacing...

متن کاملProbing the dynamics of high-viscosity entangled polymers under shear using Neutron Spin Echo spectroscopy
Neutron Spin Echo spectroscopy provides unique insight into molecular and submolecular dynamics as well as intraand inter-molecular interactions in soft matter. These dynamics may change drastically under shear flow. In particular in polymer physics a stress plateau is observed, which might be explained by an entanglement-disentanglement transition. However, such a transition is difficult to id...
