Zusammenfassung

Die Stabilität elektrostatisch oder überwiegend elektrostatisch stabilisierter Dispersionen wird durch das Potential ψ d an der Grenze zur diffusen Ionenschicht bestimmt (s. Abb. 2.6, Kap. 2.3.2 und Abb. 9.4). Im allgemeinen ist jedoch nur die Oberflächenladung, genauer die Oberflächenladungsdichte, experimentell zugänglich. Aus dieser läßt sich das Oberflächenpotential ψ 0 nach Gleichung 2.10 ausrechnen, aus dem ψ d nach dem Stern-Modell ermittelt werden kann (Kap. 2.3.2).
