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
Exfoliated polystyrene/laponite nanocomposite was synthesized successfully.

XRD patterns of nanocomposites showed the d 001 diffraction peaks of organo laponite disappeared, indicating that the laponite layers became exfoliated and disordered in result of the polymerization process; TEM photographs showed that the disordered laponite layers or primary particles with sizes about 30～100 nm were dispersed in the polystyrene matrix . TGA and DSC results showed the thermal stability and glass transition temperature of the polystyrene/organo laponite nanocomposites were obviously improved compared to that of the polystyrene.展开更多
