What is Van Der Waals Interaction Energy?

Van Der Waals Interaction Energy is the repulsive interaction energy where the force acts between two colloidal particles having a surface separation.

What is DLVO theory?

The DLVO theory explains the aggregation of aqueous dispersions quantitatively and describes the force between charged surfaces interacting through a liquid medium. It combines the effects of the van der Waals attraction and the electrostatic repulsion due to the so-called double layer of counterions.
