dc.description.abstractIn this study, polymer layered silicate nanocomposites containing polypropylene (PP), compatibilizer and organomuscovite were prepared by melt compounding. Polypropylene grafted maleic anhydride (PP-g-MAH) and polypropylene methyl polyhedral oligomeric silsesquioxane (PP-POSS) were used to compatibilize PP/muscovite systems. Muscovite clay particles were initially treated with lithium nitrate (LiNO3) and followed by cetyltrimethylammonium bromide (CTAB) through ion exchange treatment to obtained organomuscovite (OM). The presence of the alkyl ammonium ions in the OM were characterized using Fourier transform infrared (FTIR) analysis spectroscopy. X-ray Diffraction (XRD) diffractograms of OM shows that the basal spacing of muscovite was expanded from 0.99nm for the OM to 1.22nm. The stiffness and strength of PP/muscovite nanocomposites were increased with the presence of OM and compatibilizer. X-ray Diffraction (XRD) and Transmission electron microscopy (TEM) results revealed the formation of intercalated structure. Field Emission Scanning Electron Microscopy (FESEM) examination showed that the present of OM exhibit better dispersion and become more significant with the addition of compatibilizer. Furthermore, thermal analysis results revealed that melting temperature (Tm) and degree of crystallinity (Xc) of nanocomposite were reduced but the crystallization temperature (Tc) were increased with the used of OM. TGA also confirms that the thermal stability of the nanocomposites were improved with the addition of OM and compatibilizer.en_US
