Summary
Chapter 4 introduces the chemical and physical interactions that determine the nature of interfacial interactions. It includes a description of the different forces involved in long-range and short-range interactions between interfaces and between interfaces and atoms or molecules. The discussion includes ionic or coulombic interactions, dipolar and induced dipolar forces, solvation and solvent effects, and van der Waals forces. The chapter provides a low level mathematical treatment of the different interaction forces, their relative strengths, and two of the basic theories relating those forces to interfacial and colloidal phenomena—the Hamaker and Lifshitz theories.
