Abstract: Sodium montmorillonite (MMT) was modified to org anophilic montmorillonite (OMMT) by exchanging Na+ ion in MMT with trihexyltetradecylphosphonium (THTDP) ion by cation-exchange method. The OMMT was then underwent second modification involving silane coupling agent of aminopropyltrimethoxylsilane (APTMS) to produce twice-functionalized clay (grafted-OMMT). The resulting OMMT and grafted-OMMT were characterized by Fourier transform infrared (FT-IR), nitrogen adsorption-desorption and X-ray diffraction (XRD) analyses. Addition of grafted-OMMT to PMMA matrix resulted in stronger polymer-clay interaction by forming exfoliated and intercalated types nanocomposites compared to OMMT which formed conventional type composite.
