Marangoni Instability Driven by Adsorption and Association of Oppositely Charged Surfactants at an Oil–Water Interface

Marangoni Instability Driven by Adsorption and Association of Oppositely Charged Surfactants at an Oil–Water Interface

When an aqueous buffer solution of the cationic surfactant tetradecyltrimethylammonium bromide near neutral pH is contacted with a solution of the fatty acid surfactant palmitic acid in tetradecane, convective flows appear spontaneously at the interface. This coincides with turbidity formation in th...
