Complex coacervation: a field theoretic simulation study of polyelectrolyte complexation.
Using the complex Langevin sampling strategy, field theoretic simulations are performed to study the equilibrium phase behavior and structure of symmetric polycation-polyanion mixtures without salt in good solvents. Static structure factors for the segment density and charge density are calculated and used to study the role of fluctuations in the electrostatic and chemical potential fields beyo...
متن کاملField-Theoretic Simulations of Polyelectrolyte Complexation
This viewpoint article is intended as a brief introduction to the emerging subject of field-theoretic simulations (FTS) of charged polymers. While the direct numerical simulation of field theory models has begun to impact several traditional areas of polymer science, including blends and block copolymers, polyelectrolytes have hitherto not been the subject of field-theoretic simulations. Herewe...
متن کاملCluster formation in polyelectrolyte-micelle complex coacervation.
The temperature-induced liquid-liquid phase transition (complex coacervation) of a polycation-anionic/nonionic mixed micelle system was examined over a range of macroion concentrations and polycation molecular weights (MW) using turbidimetry and dynamic light scattering (DLS). DLS revealed a progressive increase in complex/aggregate size with temperature up to the phase transition at T(φ), foll...
متن کاملIPEC Solver: Numerical simulation tool to study inter-polyelectrolyte complexation
IPEC solver is a windows program designed to analyze the stability of core-shell interpolyelectrolyte complexes formed by complexation of oppositely charged block co-polymers. The two-dimensional size distribution (number of anions and cations) of the complexes is calculated based on the scaling model of block co-polymer aggregation and Poisson-Boltzmann theory for electrostatic interactions (V...
متن کاملEffects of Salt on Polyelectrolyte-Micelle Coacervation
Turbidity, dynamic light scattering, and electrophoretic mobility were used to study the effects of added salt on coacervation in the system composed of the strong cationic polymer poly(diallyldimethylammonium chloride) (PDADMAC) and oppositely charged mixed micelles of Triton X-100 (TX100) and sodium dodecyl sulfate (SDS). The phase behavior in the range of ionic strengths from 0.05 to 0.60 M ...
