Volume 2 of the Handbook of Colloid and Interface Science is a survey into the theory of dispersions in a variety of fields, as well as characterization by rheology. It is an ideal reference work for research scientists, universities, and industry practitioners looking for a complete understanding of how colloids and interfaces behave in the areas of materials science, chemical engineering, and colloidal science.

A colloidal dispersion is a two-phase system in which one phase (the disperse phase) is dispersed in a second continuous phase (the dispersion medium). The disperse phase can be solid, liquid or gas and the same applies for the dispersion medium. On this basis one can distinguish several classes of colloidal dispersions: solid/liquid (suspension), liquid/liquid (emulsion), gas/liquid (foam), liquid/gas (aerosol), liquid/solid (gel), solid/gas (smoke) and solid/solid (composite). Another important class of colloids are produced by self-assembly of surfactants that form micelles with dimensions in the colloid range and these were described in Vol. 1.

In all disperse systems such as suspensions, emulsions, foams, etc., the structure of the interfacial region determines its colloidal properties. For convenience, I will list the topics of colloid and interface science under two main headings: disperse systems and interfacial phenomena. This subdivision does not imply any separation for the following reasons. All disperse systems involve an interface. Many interfacial phenomena are precursors for formation of disperse systems, e.g. nucleation and growth, emulsification, etc. The main objective of the present handbook is to cover the following topics: the basic principles that are involved in the formation of colloidal dispersions and their stabilization.

The field of colloid and interface science has no boundary since chemists, physicists, engineers, biologists, and mathematicians can all be engaged in the field. For successful applications in industry, multidisciplinary teams are required. Understanding the basic principles of colloid and interface science will enable industry to develop many complex systems in a shorter period of time. Most colloidal systems used in industry are multiphase and complex formulations. They may contain more than one disperse phase, e.g. suspension/emulsion systems (suspoemulsions).
