We explore the reentrant condensation of polyelectrolytes triggered by multivalent salts, whose phase-transition mechanism remains under debate. propose a theory to study condensation, which separates electrostatic effect into two parts: short-range gluonic because sharing ions ionic monomers and long-range correlation from all ions. The suggests that governs requiring minimum coupling energy initiate phase transition. This explains why diluted salts with selective multivalency trigger polyelectrolyte also uncovers strong adsorption onto causes low-salt concentrations induce both collapse reentry transitions. Additionally, we highlight how incompatibility uncharged moieties water affects behaviors. obtained results will contribute understanding biological separations if bound biopolyelectrolytes play an essential role.

Polymer association at liquid-liquid interfaces is a promising way to spontaneously obtain soft self-healing membranes. In the case of reversible bonding between two polymers, macromolecules are mobile everywhere within membrane and they can be absorbed into it both boundaries due binding other type. this work, we develop theoretical model growth based on these assumptions.

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 which transient interactions play an important role. In this work, we investigate properties charged blends whose constituents are capable creating dynamic bonds. We model bonds harmonic springs with additional bond formation energy, εa, be adjusted influence reaction rates for binding unbinding. show that varying number sites on chains εa has a effect resulting phase diagram. further diffusive behavior coacervates. how network structure changes active site, increasing identify values result percolation. Lastly, explore possibility inducing orthogonal separation by introducing second type cannot interact first kind.
