Résumé : |
The development of pigment dispersants for waterborne or solvent-borne paint systems requires knowledge about anchoring groups, soluble tails, and about an effective and practically feasible architecture to build them together into one molecule.In this paper a method is described for the comparison of the anchoring properties of functional groups. The adsorption of model compounds to pigments from an aqueous solution is measured. From the adsorption isotherms thus obtained, the free energy of adsorption can be calculated, as well as the number of anchoring groups that can adhere to a given weight or surface area of pigment. |
