Abstract
Solution atomic force microscopy imaging of the adsorbed layer of tetradecy ltrimethylammonium bromide on kaolinite and montmorillonite particles depos ited onto mica shows a strong dependence of film morphology on clay substra te. Whereas stripes (cylindrical micelles) are observed on mica, spherical structures are seen on both kaolinite and montmorillonite particles under i dentical solution conditions.
