Colloidal dispersions are a class of soft materials. The term typically refers to a material consisting of solid particles spread throughout a fluid. According to Jones [1, p. 49], colloidal particles must have dimensions on the order of 10<math>\mu</math>m or smaller.
Witten [2, p. 113] distinguishes between colloids (solid particles in liquid), emulsions (liquid drops in another liquid), and foams (gas bubbles in a liquid), while Jones [1, p. 1] includes emulsions as a subgroup of colloidal dispersions. One can also find definitions of colloidal dispersions which include other combinations of solid, liquid, and gas phases.
