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. [WT5HZ]展开更多

A transmission 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.展开更多
