摘要

Polystyrene/clay nanocomposites were prepared and modified by SBS and catalyzed metallocene ethylene octene copolymer. The results indicated an improvement in mechanical properties of the nanocomposite contained 1 w% of nanoclay. X- Ray analysis revealed that only intercalated structures were found in the nanocomposites. Scanning electron microscopy (SEM) showed a homogenous morphology for the nanocomposites due to compatibility between polystyrene and styrene butadiene styrene. Energy dispersive X-ray (EDX) analysis also confirmed a sufficient dispersion and distribution of Si elements from nanoclay in the PS/SBS matrix. Thermal stability of the nanocomposites was studied by heat deflection temperature (HDT) and also thermo gravimetric analysis (TGA). It was found that HDT and thermal degradation were enhanced for the nanocomposite which was contained 1 w% of clay nanoparticles compared to the neat polystyrene.
