| Abstract:Surface elemental compositions of model clay/latex coatings consolidated under various conditions were measured using XPS technique, in order to elucidate the moment when the migration of particulate latex relative to pigments during drying of colloidal suspensions takes place. The results showed that surface carbon content was higher for coatings dried at a higher temperature, and surface carbon content reduced greatly as delaying drying at room temperature. The observations provided evidence that latex migration mainly took place after coating application but before capillary formation, i.e., when the coatings were in liquid phase. |
