Consistent Surface Potentials from Bulk Suspension Properties
The equilibrium mechanical properties of face centered cubic (FCC) colloidal crystals interacting through the Yukawa potential are investigated. We investigate the use of a screened Coulomb interaction potential to define a single, electrostatic surface potential capable of predicting both the elastic modulus and osmotic pressure of colloidal crystals. Correlations are developed which capture the volume fraction, particle size, and ionic strength dependencies of these properties. Copyright 1997 Academic Press. Copyright 1997Academic Press
