FIGURE12.4 Examples of the colloidal interaction energyVT(in units ofkBT) as a function of interparticle distanceh, calculated
according to the DLVO theory for spherical particles in an aqueous phase. Illustrated are the effects of the magnitude of (a) the
Hamaker constantA; (b) surface potentialjc 0 j; (c) ionic strengthI; and (d) particle radiusR. Unless indicated otherwise,
A¼1.25kBT;jc 0 j¼15 mV;I¼10 mmolar;R¼ 1 mm. x, y, and z denote the maximum, the primary minimum, and the secondary
minimum inVT, respectively.
