Critical Fluctuations in Polymer Solutions: Crossover from Criticality to Tricriticality
Mikhail A. Anisimov, Thomas J. Longo, Jan V. Sengers
Critical fluctuations in fluids and fluid mixtures yield a nonanalytic asymptotic Ising-like critical thermodynamic behavior in terms of power laws with universal exponents. In pol…
Physical origin of the expansion of polymer coils in a binary solvent in the vicinity of its demixing critical point
Jan V. Sengers, Mikhail A. Anisimov, Xiong Zheng
Critical fluctuations are known to induce a collapse of polymer chains in a mixed solvent upon approaching its liquid-liquid critical point, as originally predicted by Brochard and…
Unusual transformation of polymer coils in a mixed solvent close to the critical point
Xiong Zheng, Mikhail A. Anisimov, Jan V. Sengers +1
We have discovered unusual behavior of polymer coils in a binary solvent (nitroethane+isooctane) near the critical temperature of demixing. The exceptionally close refractive indic…
Probing structural relaxation in complex fluids by critical fluctuations
A. F. Kostko, M. A. Anisimov, J. V. Sengers
Complex fluids, such as polymer solutions and blends, colloids and gels, are of growing interest in fundamental and applied soft-condensed-matter science. A common feature of all s…
Scaling of demixing curves and crossover from critical to tricritical behavior in polymer solutions
J. S. Hager, M. A. Anisimov, J. V. Sengers +1
In this paper we show that the virial expansion up to third order for the osmotic pressure of a dilute polymer solution, including first-order perturbative corrections to the viria…
Dynamic Crossover to Tricriticality and Anomalous Slowdown of Critical Fluctuations by Entanglements in Polymer Solutions
A. F. Kostko, M. A. Anisimov, J. V. Sengers
We have performed accurate dynamic light-scattering measurements near critical demixing points of solutions of polystyrene in cyclohexane with polymer molecular weight ranging from…
