Negative charges at the air/water interface and their consequences for aqueous wetting films containing surfactants
Abstract
Negative charges at the air/water interface have been proven previously by the authors via disjoining pressure measurements of wetting films. In the present study the surface charges of wetting film are modified in order to control the film stability. Studies at different pH values support the assumption that the negative charges are caused by an excess of
