Abstract:
This paper describes the preparation and characterization of polypropylene (PP)/multiwall carbon nanotubes (MWCNTs) nanocomposites. Two types of commercial MWCNTs at two different loadings (1 and 3 wt%) were added in PP via melt compounding method by using a twin screw extruder. Afterward, the molded samples were fabricated from the extrudate pellets using an injection molding machine. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to study the crystallization behavior and thermal stability properties of the nanocomposites. The DSC results revealed that the presence of MWCNTs in PP matrix acted as nucleating agent, which enhanced the crystallization process of PP matrix. Meanwhile, the TGA results showed that the addition of MWCNTs dramatically increased the thermal stability of PP/MWCNTs nanocomposites. Generally, MWCNTs type C-70P showed a better improvement on crystallization and thermal stability properties compared to type C-150P.
