Summary

Rate of expansion of three-phase contact perimeter at monolayers of octadecyl amine (substrate:quartz) of different numbers was investigated and the results were discussed on the basis of a theory for dimple formation. Correlations between adsorption density of surfactant at the liquid/gaseous interface, velocity of three-phase contact perimeter and induction time are presented.

Zusammenfassung

Es wurde die Ausbreitungsgeschwindigkeit des Dreiphasenkontaktperimeters auf Monoschichten von Octadecylamin (Substrat:Quarz) unterschiedlicher Zahl untersucht und die Ergebnisse auf Grundlage einer Theorie zur Dimplebildung diskutiert. Korrelationen zwischen der Adsoptionsdichte an Tensid an der Grenzfläche flüssig/Gas, der Geschwindigkeit des Dreiphasenkontaktperimeters und der Induktionszeit werden aufgezeigt.
