Dendritic Surfactants Show Evidence for Frustrated Intercalation: A New Organoclay Morphology [PDF]

open access: yes, 2003
Mixing a smectite clay with some dendritic surfactants shows that despite the large size of some of these molecules, a property that frustrates complete intercalation into the gallery of the clay, organoclay materials are obtained.
