Abstract
Dispersed systems consisting of fluids are represented by emulsions and foams. Colloidal particles act as efficient stabilizers for the dispersed systems, like conventional surfactants, by adsorbing at the fluid interfaces. The wettability of colloidal particles at fluid interfaces has been thought to be one of the most important factors to control properties of the fluid dispersed systems. Herein several ways to tune particle wettability in stabilizing fluid dispersed systems consisting of air and liquids are presented with an emphasis to describe incorporation of surface roughness effects into particle wetting of particles at fluid interfaces.
