Abstract

PP and 6 wt % organoclay nanocomposite was produced by melt blending and followed by injection molding. 0 wt %, 5 wt %, 15 wt %, and 20 wt % of the NR were added into the PP/ Organoclay nanocomposite with 6 wt %PPgMAH ascompatilizer. The mechanical properties were studied by tensile and impact testing while the morphology was studied by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). XRD was used to characterize the intercalation and determined d-spacing of the silicate layer in the nanocomposite, whereas SEM was used to observe the dispersion of NR particle in PP/ F6/ C6 nanocomposite. The result showed that with the incorporation of NR into PP/ F6/ C6 nanocomposite, both of the Young's Modulus and tensile strength decreased when NR content increased, and inversely the impact strengths increased when added NR content increased. From the XRD measurement, the peak angles of NR toughened PP/ F6/ C6 nanocomposites were shifted to smaller angle when NR content increased in PP/ F6/C6 nanocomposite and d-spacing did not show an apparently changes when NR were added into PP/ F6/ C6 nanocomposite. From the SEM image, the NR particles were well dispersed in PP/ F6/ C6 nanocomposite and the particle sizes were in the range between 0.2 µm to 5.5 µm. Finally, 12 wt % NR was determined as the optimum concentration in NR toughened PP/ F6 / C6 nanocomposite.
