Abstract
Nanocomposites of polyphenylene sulfide (PPS) were prepared with a benzimidazolium surfactant used as organic modification for the montmorillonite (MMT) by melt blending. The benzimidazolium-modifided MMT( Bz-MMT) exhibited a large interlayer spacing of 3.26 nm and showed a high thermal stability compared to the commonly used clay modified by alkyl ammonium salts(DK-1N). The morphology of the polyphenylene sulfide (PPS)/Bz-MMT nanocomposites were evaluated by X-ray diffraction (XRD) and transmission electron microscope (TEM). The results showed good overall dispersion of the MMT in PPS matrix. Thermogravimetric analysis (TGA) were used to evaluate the thermal properties of polymer/clay nanocomposites. The results of TGA showed the thermal stability of the polymer/clay nanocomposits was enhanced.
