Cluster 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 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 ...
متن کاملComplex 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 کاملEarly stage kinetics of polyelectrolyte complex coacervation monitored through stopped-flow light scattering.
Polyelectrolyte complexes (PECs) between poly(acrylic acid) (PAA) and poly(diallyldimethylammonium chloride) (PDADMAC), a model system forming coacervate particles via electrostatic interaction at pH 10, were prepared by a stopped-flow (SF) fast mixing technique at different mixing charge ratios (z) and ionic strengths. Both PEC final morphologies prepared by either SF or manual one-shot mixing...
متن کاملComplex Formation between Polyelectrolyte and Oppositely Charged Mixed Micelles: Soluble Complexes vs Coacervation
The system comprised of poly(dimethyldially1ammonium chloride) (PDMDAAC) and oppositely charged mixed micelles of Triton X-100 (TXlOO) and sodium dodecylsulfate (SDS) displays several states, including coacervate and various soluble complexes. The phase boundary for the equilibrium between soluble complexes and coacervate (“associative phase separation” according to Piculell and Lindman) for 0....
