| Résumé : | This article reports the results of experiments conducted on the spontaneous climbing of an aqueous film of trisiloxane surfactants (“superspreaders”) on a vertical strongly hydrophobic solid surface. The final height achieved is much in excess of that expected purely on the basis of the capillary wetting action and suggests that a spontaneously developing surface tension gradient aids in film climbing. Maxima are observed in both the spreading rate and the height achieved as a function of the surfactant concentration, similar to the spreading of a superspreader drop on a horizontal hydrophobic surface. |
