WebApr 7, 2024 · The DLVO theory takes account of two types of force in a stable colloid: the van der Waals' force, which is attractive and binds particles together, and electrostatic repulsion. The total interaction potential can be calculated as a function of distance, with colloid stability being attained when the two forces balance each other. Web(DLVO) theory. This model is based on the balance be-tween van der Waals attraction and electrostatic repulsion [1,2]. While appropriate for a wide variety of systems, the DLVO approach failed to account for some experimentally observed features of stability behavior.
