CoachCoagulation is the aggregation of colloidal particles caused by the loss of their electrostatic repulsion; flocculation is aggregation into loose flocs, often bridged by adsorbed polymers. The critical coagulation concentration (CCC) of an electrolyte is the concentration above which a colloid coagulates rapidly. Steric stabilisation keeps particles apart with adsorbed or grafted polymer chains, whose overlap would cost entropy.
