Colloid stability in aqueous and non-aqueous media. Introductory paper

Abstract

Colloid stability is determined by the interaction between particles during a (Brownian) encounter. The forces playing a role in encounters (van der Waals forces, double-layer interaction, interaction between adsorbed molecules, such as surfactants, polymers and small molecules) are discussed with emphasis on unsolved problems. It is pointed out in which of the papers of this Discussion the different problems are treated.
