| Summary: | This paper presents the effect of filler loading to compounding torques as well as mechanical
properties of PP/MWCNTs nanocomposites. Samples were prepared via melt compounding method using
a Haake internal mixer at rotor speed of 80 rpm. The torque values in 10 minutes compounding period for
incorporation of MWCNTs fillers into PP matrix were analyzed and thoroughly evaluated. The data was
further confirmed by morphological analysis via transmission electron microscopy (TEM). The efficiency
of direct melt-compounding method using internal mixer was evident from homogeneity of MWCNTs
dispersed within the PP matrix observed in produced nanocomposites at filler loading up to 0.75 wt%.
MWCNTs showed significant compatibility with PP matrix and proved the needlessness of chemical pre-
treatment and complicated compounding process to produce PP/MWCNTs nanocomposites. The
mechanical properties and morphological characteristics were in good correlation with the processing
behavior of the nanocomposites
