Steric or Entropic Stabilization

Figure 10.4 Schematic representation of the electrical double-layer forces (a) and of the steric (or entropic) stabilization (b). The latter Is obtained using adsorption of oligomers or polymers. The "hairy" surface prevents flocculation of the particles. This is the reason for very good stability of solvent-based coatings, where binder molecules can adsorb on the pigment particles...
