In this study, physical and mechanical properties of polypropylene nanocomposites in the presence of carbon nanotubes (MWCNT) were studied. Nanocomposites were prepared by combining different percentages of MWCNT with PP using melt mixing method. The mechanical and physical properties such as the fracture surface morphology, distribution of CNTs in the material field, the size of the crystals, crystallization and melting temperature, tensile strength, flexural and impact strength and flexural modulus were analyzed. In summary, it was shown that Young's modulus and flexural an increase in the weight of MWCNT, are considerably improved. However, the distribution of the nanotubes was poorer in material terms, the melting temperature has not noticeably changed. Also, the sizes of the crystals in some Miller's pages were decreased. By increasing the amount of MWCNT, an increase in crystallization temperature of PP was observed. Loading 1.5%wt of MWCNT, the amount Tp has increased with about 14.3°C than pure PP. By increasing the MWCNT to 0.4%wt, the mechanical properties were improved. Then changing MWCNT to 0.8%wt, the mechanical properties was reduced.
