Interplay of distinct modes of charge regulation on poly-acid ionization and conformation
Souradeep Ghosh, Aritra Chowdhury, Dylan T. Tomares +3
We adapt the Edwards-Muthukumar theoretical framework for a single polymer chain to investigate the interplay between proton binding and counterion condensation for poly-acids. We…
Effect of Counterion Size on Polyelectrolyte Conformations and Thermodynamics
Souradeep Ghosh, Arindam Kundagrami
We present a theoretical model to study the effect of counterion size on the effective charge, size, and thermodynamic behavior of a single, isolated, and flexible polyelectrolyte…
Polymer Complexation: Partially Ionizable Asymmetric Polyelectrolytes
Souradeep Ghosh, Soumik Mitra, Arindam Kundagrami
Studies of the thermodynamics of complex coacervation of pairs of symmetric, strongly ionizable, oppositely charged polyelectrolyte chains are abundant. To generalize such understa…
Polyelectrolyte Complexation of Two Oppositely Charged Symmetric Polymers: A Minimal Theory
Soumik Mitra, Arindam Kundagrami
Interplay of Coulomb interaction energy, free ion entropy, and conformational elasticity is a fascinating aspect in polyelectrolytes (PEs). We develop a theory for complexation of…
Effective charge, collapse and the critical point of a polyelectrolyte chain
Arindam Kundagrami, M. Muthukumar
The charge of a polyelectrolyte (PE) controls myriads of phenomena in biology, biotechnology, and materials science, but still remains elusive from an understanding. Considering th…
The collapse of linear polyelectrolyte chains in a poor solvent: When does a collapsing polyelectrolyte collect its counter ions?
Peter Loh, G. Roshan Deen, Doris Vollmer +4
In order to better understand the collapse of polyions in poor solvent conditions the effective charge and the solvent quality of the hypothetically uncharged polymer backbone need…
