In this paper, metallocene polypropylene (mPP) composites ﬁlled with carbon nanotubes (CNTs) were prepared using twin-screw extruder. The crystallization behavior, mechanical properties and rheological behavior were characterized by a differential scanning calorimetry (DSC), universal material testing machine and rotational rheometer. The results of DSC indicated that the effect of CNTs on heterogeneous nucleation of mPP was very obvious and the crystallizability of the resin matrix was improved after adding CNTs, especially the initial crystallization temperature (T0), crystallization temperature (Tc) increased by 9.63 °C and 8.28 °C when the CNTs content was 1.25 wt%. The yield stress and elastic modulus increased to 33.98 MPa and 1605.6 MPa as the CNTs concentration increased to 1.0 wt.% in contrast to that of the neat mPP. The results of SEM images showed that the better dispersion and adhesion of CNTs into polymer matrix. The results of rotational rheometer proved that interactions increased between CNTs and mPP as the content of CNTs increasing.

Aims: The aim of this study was to evaluate the mechanical properties of polymer nanocomposites (PNCs) reinforced with multiwalled carbon nanotubes (MWCNT). Methods: Mixing MWCNT into the polymer at very small propositions can enrich the mechanical properties of the polymer nanocomposites. Testing Specimen fabricated with 0.1wt%, 0.5wt%, 1wt% mixing ratios using extrusion and injection molding process. Computational analysis was performed through the square RVE model and analyzed with finite element analysis (FEA) using DIGIMAT simulation tool. The specimen was evaluated by ASTM D3039 for tensile strength and ASTM D7264 for flexural. Results: The simulated results were compared with experimental results. Scanning electron microscopy(SEM) was performed to evaluate the dispersion state of nanotubes in the matrix. Conclusion: The impactful improvement in mechanical properties is shown in the results after addition of functionalized MWCNTs (f-MWCNT) compared to pure polymer and non- functionalized MWCNT composites.
