Abstract
- Abstract: In this work, properties from colloidal silica containing foam systems were analyzed and correlated to the fundamental concepts of the particle adsorption at the gas–liquid interface, specifically for the adsorption energy and its relationship to the thermal energy of the particle. Based on the presented data, it can be pointed out that hydrophilic colloidal particles should give rise to unstable foams due to their low adsorption energy, which is below the minimum threshold required evaluated for the particle containing foam stabilization.
