“…All lengths are reported in units of the statistical segment length of the polymers, denoted as b and set to unity. Our previous work has demonstrated that systems of this size are should be free of finite-size effects . The simulations are initialized from a dense “slab” which is placed in the center of the box, and the polymers are allowed to relax away from this dense state during the equilibration procedure.…”

“…Our previous work has demonstrated that systems of this size are should be free of finite-size effects. 60 The simulations are initialized from a dense "slab" which is placed in the center of the box, and the polymers are allowed to relax away from this dense state during the equilibration procedure. This allows us to efficiently generate a single, polymer-rich phase without the need to wait for coarsening dynamics of droplets formed randomly in our simulation box.…”

Associative polymer networks have shown major promise in the fabrication of self-healing and responsive materials. They can also serve as simple models to study more complex biological systems in which transient interactions play an important role. In this work, we investigate the properties of charged polymer blends whose constituents are capable of creating dynamic bonds. We model dynamic bonds as harmonic springs with additional bond formation energy, ε a , which can be adjusted to influence the reaction rates for binding and unbinding. We show that varying the number of binding sites on the chains and ε a has a major effect on the resulting phase diagram. We further investigate the diffusive behavior of the coacervates. We also study how the network structure changes with varying number of active site, and increasing ε a , and identify the values which result in the network percolation. Lastly, we explore the possibility of inducing orthogonal phase separation by introducing a second type of binding site, which cannot interact with the first kind.

The effect of monomer polarizability on the stability and salt partitioning in model coacervates

Abstract: Coacervation of charged polymer chains has been a topic of major interest both in polymer and biological sciences, as it is a subset of a phenomenon called liquid-liquid (LLPS) phase...
