Abstract: An infrared dichroism study on the orientation of PSin the shear-induced ordered structure in PS/montmorillonite nanocomposite was carried out. The results showed that the phenyl ring oriented apparently parallel to the film surface, whereas no obvious orientation of the aliphatic chain could be observed. On the basis of both of our previous and present investigations, a possible formation mechanism was presented.

Key words: Nanocomposite, PS, Shear-induced ordered structure, Infrared dichroism
