Mechanical and Morphological Properties of PP/MWNT/MMT Hybrid Nanocomposites

摘要

Polypropylene/Multiwall carbon nanotubes/Montmorillonite (PP/MWNTs/MMT) hybrid nanocomposites were prepared by using twin-screw extruder incorporating the polypropylene grafted maleic anhydride (PP-g-mA) as compotibilizer is used for better dispersion of nanoclay in the polymer matrix. The effect of MWNTs and MMT on the polypropylene matrix was investigated in terms of mechanical properties of tensile, flexural, impact and morphological properties using Transmission electron microscope (TEM), X-ray diffraction (XRD) and scanning electron microscope (SEM). These were compared with the pure PP matrix. The resulting composite shows about 81% increase in tensile modulus and 96% in the impact strength when compared with pure PP.
