AbstractFourier Transform Infrared (FTIR) Spectroscopy and Wide Angle X-ray Diffraction (WAXD) techniques were used to study a selective modification of montmorillonite with hydroxyl group (-OH) of toluene-2,4-di-isocyanate (TDI). Based on the investigation results,a schematic model was presented. The selective modification product was applied to prepare an intercalated polystyrene/montmorillonite nanocomposite,and the nanocomposite was characterized by WAXD and Transmission Electron Microscopic (TEM) techniques. The FTIR results showed that after modification of cetyltrimethylammonium bromide (CTAB) exchanged montmorillonite, TDI was successfully selectively grafted to the surface -OH group of the montmorillonite via two different synthetic routes. And the WAXD results revealed that the interlayer distance of the montmorillonite was increased dramatically. Combining with the previous investigations,it may be deduced that the orientation of the CTAB might be changed from a bilayer structure parallel to adjacent silicate layers in CTAB-exchanged montmorillonite to a double layer inclined structure in the interlayer space of the TDI grafted montmorillonite product. The TDI modified montmorillonite product could be successfully applied to obtain an intercalated polystyrene/montmorillonite nanocomposite. During the intercalative polymerization process,the interlayer distance of the TDI modified montmorillonite was increased further. Five sharp diffraction peaks, d(001) = 4.24,4. 60,5. 07,6. 59,7. 48nm,appeared for the polystyrene/TDI modified montmorillonite nanocomposite. The TEM investigation indicated that the thickness of the montmorillonite primary particles was reduced to 20 similar to 50nm in the polystyrene matrix. The WAXD and TEM results suggested that an,intercalated polystyrene/TDI modified montmorillonite nanocomposite was successfully achieved.
