摘要
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.
