ABSTRACT
I. INTRODUCTION TO COLLOIDAL DISPERSIONS Colloidal dispersions are finely subdivided systems of dispersed phase in a dispersion medium. This fine subdivision creates a very high specific surface area (area per unit weight) and determines largely the physical properties of the dispersion. In the most common dispersion the continuous phase (dispersion medium) is a liquid, but it can also be a solid or a gas. To be considered a colloid, the liquid droplets or the solid particles in a liquid dispersion have to have a size in diameter between one nanometer (nm) and one micrometer (jxm).
