| Popis: | Polystyrene (PS)/clay nanocomposites were synthesized by the emulsion polymerization of styrene in the presence of sodium ion-exchanged montmorillonite (Na+-MMT), demonstrating that the strongly hydrophobic PS was intercalated into the hydrophilic silicate layers. The nanocomposites were examined by means of X-ray diffraction, transmission electron microscopy, thermogravimetric analysis. The rheological properties of the PS/Na+-MMT nanocomposites were also studied to exhibit more pronounced shear thinning behavior with increasing clay content. |
