Abstract
Our measurements of the surface tension of charge‐stabilized TiO2 and SiO2 dispersions show that the surface tension of the dispersions is a function of the particle concentration. At lower concentrations, the adsorption of particles to the interface decreases the total free energy of the system which causes a decrease in the surface tension. At higher particle concentrations, the attractive capillary forces between particles at the surface increases the amount of work it takes to deform the surface, which increases the surface tension. Compared with the surface tension of TiO2 dispersions, the decrease of the surface tension of SiO2 dispersions is slightly less and the minimum surface tension occurs at a higher particle concentration. The reason is believed to be the larger particle size of the SiO2 particles.
