FIGURE 6.12 The scaled interaction free energy between two equal-sized spheres, with Ka = 10 a being the sphere radius) for several values of the dimensionless surface potential and at various ratios of the surface potentials. Results are shown for (a) constant potential interaction with 2/ 1 = (b) constant charge interaction with = 3. [Pg.180]
