Abstract: A shear-induced ordered structure in PS/montmorillonite nanocomposite was observed for the first time by wide angle X-ray diffraction technique. Atransmission electron microscopy result showed that the randomly placed primary particles of montmorillonite were oriented parallel to the pellet surface, and the interior of the primary particles became more ordered as well. These results suggested that the orientation of the primary particles as well as the interior ordered structure induced by the shear flow were perhaps the origin of the ordered structure in the PS/montmorillonite nanocomposite.

Key words: Nanocomposite, PS,Montmorillonite, Shear-induced ordered structure
