“…In addition to hydrogen bonding, metal complexation is another useful interaction for building linear supramolecular polymers [24], gels [121], and networks [122]. For this purpose, a variety of different ligands have been developed, as summarized in Scheme 2.…”

“…We note that temperature or chemical modification of the solvent may affect the strength of the stickers, e.g. an increase of temperature deactivates hydrogen bonds; counter-ions inactivates metal-ligands stickers [37]. These might also affect the rate at which supramolecular bonds are formed and broken.…”

We present a simplified stochastic model designed to exemplify the non-linear rheology of entangled supramolecular polymeric materials. We have developed a simplified stochastic model for the rheology of entangled telechelic star polymers. As a toy model for entanglement effects, we use the Rolie-Poly equations [1] that we decorate with finite extensibility. Additionally, we include a stretch-dependent probability of detachment for the stickers. In both linear and non-linear regimes, we explore the parameter space, indicating the parameter values for which qualitative changes in response to the applied flow are predicted. Theory and results in the linear rheology regime are consistent with previous more detailed work of van Ruymbeke and co-workers [2]. Finally, we develop a pre-averaged version of the stochastic equations described above to obtain a set of non-stochastic coupled equations that produces very similar predictions but requires less computing resources.This pre-averaged model is based on two tensors representing the attached and detached chain populations and a scalar quantity that represents the fraction of these populations. * mmvahb@leeds.ac.uk

AbstractWe investigate shear flow instabilities using a recently-derived constitutive law, designed for describing the rheology of entangled telechelic polymers. The continuum model displays shear banding, often accompanied by a strong elastic recoil in the transient response, which appears as an "apparent" wall slip. For certain parameters, the model also displays a novel "apparent" stick-slip behavior, giving rise to strong nonlinear oscillations in the stress response driven by a repeating cycle of elastic recoil followed by diffusive rehomogenization of the flow. We elucidate the detailed mechanism behind this oscillatory response, demonstrating that it arises from a competition between shear-induced breaking of sticky bonds, which leads to recoil and banding, and a diffusive rehomogenization of the flow. We discuss the relation between the apparent stick-slip in our continuum model with similar behavior in "true" wall slip. * d.j.read@leeds.ac.uk
