A shear-induced ordered structure in PS/montmorillonite nanocomposite (I) - Wide angle X-ray diffraction and transmission electron microscopy studies

A shear-induced ordered structure in PS/montmorillonite nanocomposite was o bserved for the first time by wide-angle X-ray diffraction technique, A tra nsmission electron microscopy result showed that the randomly placed primar y particles of montmorillonite were oriented parallel to the pellet surface , and the interior of the primary particles became more ordered as well, Th ese results suggested that the orientation of the primary particles as well as the interior ordered structure induced by the shear flow were perhaps t he origin of the ordered structure in the PS/montmorillonite nanocomposite.
