| 제목 | Syndiotactic polystyrene / organophilic clay nanocomposites : |
| 초록 | Recently polymer and clay hybrid, called nanocomposite has been receiving special attention because of its various advantages in comparison to the traditional polymer composites. Nanocomposites show enhanced mechanical and thermal properties at even small amount of clay because of the large contact area between polymer and clay through nano-scaled hybrid so that the nanocomposites are free from the above weak points of the traditional polymer composites. In this article we attempted to fabricate the nanocomposite of syndiotactic polystyrene (sPS) / clay system by melt intercalation. Syndiotactic polystyrene / clay were prepared by melt blending the polymer with montmorillonite modified by alkyl phosphonium cation. Clay dispersion was analysed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Mechanical and thermal properties were studies as a function of filler content by tensile testing, Izod impact testing, thermogravimetric analysis and differential scanning calorimetry. Effect of dispersed silicates on the mechanical properties, thermal stability and flame resistance of sPS nanocomposites was considered. |
