The Hamaker constants are usually inserted in expressions for the potential energy of interaction between particles and surfaces. For a spherical particle-planar slab surface interaction of the same material, for the ( RSph D) case, if we combine Equations (533) and (536), we have... 

In order to describe the stability of fine disperse systems stabilized by diffuse ionic layers, one has to use the total free energy of interaction between particles, instead of the energy per unit film area, and compare the barrier height,, to the thermal energy, kT. For us to be able to use the solution derived for the case of plane-parallel surfaces, let us introduce some effective area of particle contact, Se[. Then the potential barrier height for the particles can be expressed as = A5 max St(. When diffuse part of electrical double...

Figure 8 Free energy of interaction between particles of chotesierol immetsed in sut. tion.s of sodium cholaic of differem concentrations. (From data in Ref. 47.)...

FIGURE 4.46 A comparison of the force-distance curve, and the free energy of interaction, F(h) = ACf (h) (a), with the energy of interaction between particles, h j(/j) (b-d). These results explain why F(h) and p (h) are insensitive to the addition of electrolyte, while the latter makes a significant impact on the Wi(h) curve and the primary minimum depth. This impact is visible when the minimum is lOkT. (Data from Shchukin, E.D. and Yaminskiy, V.V., Colloids Surf., 32, 19, 1985.)... 

Chemical constitution, polarity Influences viscosity through the effect on potential energy of interaction between particles, solubility of resin, and viscosity. 

The type of interaction between colloidal electrically charged particles in a liquid medium can be estimated by the DLVO theory (1 -4,23). According to this theory, the extent of agglomeration in colloidal suspensions depends on the total potential energy of interaction between particles (Ut), which consists basically of a balance among the attractive ( /a) and repulsive Ur) potential energies, as follows ... 

For aqueous systems, the free energy of interaction between particle or molecule, 1, and solid substratum, 2, immersed in water, w, is described by (cf. Eq. 6.50) ...
