Abstract
Five sandwiched multilayers consisting of PBT(Polybutyleneterephthalate), PS(Polystyrene) and clay were prepared to investigate the migration mechanism of clay in the polymer blend system. Rheometry (RMS800) was used to apply well-defined shear on the above multilayer samples in order to well understand dominant factors controlling the migration. Applied shear force was enough to move clay tactoids to the interface, if either long time or high shear was available, but it was not sufficient to separate into individual platelets of clay. The morphology evolution was subsequently studied in term of scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HR-TEM), respectively.
