摘要：

The forces between silica surfaces in the presence of poly(acrylic acid) solutions have been measured as a function of polymer concentration using an atomic force microscope. Under similar solution conditions to the force-distance studies, the stability of a colloidal silica dispersion to depletion flocculation was studied. The measured force-distance curves were used to interpret the observed flocculation behaviour of the dispersion.
