DLVO demo
- This is an interactive Flash* movie made by Brian Prevo demostrating the interplay of van der Waals attraction and electrostatic repulsion for colloidal particles at different ionic strengths. For either case, the Hamaker, A, constant was chosen to represent polystyrene (log A = -20), the particle diameter is 100 nm, the surface potential is in the "low" regime, at 15 mV, and the solvent medium (water) has a 1:1 electrolyte like NaCl. As the ionic strength changes, the degree of electrostatic stabilization changes.
