Thermodynamic properties and rheology of sterically stabilized colloidal dispersions

A procedure for predicting thermodynamic, dynamic, and rheological properti es of polymerically stabilized colloidal dispersions in good solvents by ma pping onto an effective hard sphere dispersion is investigated and evaluate d for its range of applicability. Configurational pressures and energies, c alculted by Monte Carlo simulations, are used to assess the model's accurac y for predicting thermodynamic data. Similarly, long-time self-diffusivitie s, calculated by equilibrium Brownian Dynamic simulations, are used to asse ss the model's feasibility for predicting dynamic properties. Finally, zero shear viscosities are calculated by the method of hydrodynamic preaveragin g and compared to rheological measurements. The various testing methods dem onstrate the effectiveness of the procedure and suggest the model's range o f applicability.
