Abstract

The influence of the anionic surfactant sodium dodecyl sulfate (SDS) on the evaporation of drying silica colloidal droplets is investigated. The addition of SDS leads to an attenuation of cracks patterns after evaporation (i.e., the presence of cracks in the structure are dramatically altered). We understand that this phenomenon could be induced by radial Marangoni flows induced by the variation of SDS concentration along the air-water interface along with a depletion flocculation.
