| Summary: | This article presents the effect of filler loading on compounding torques as well as
mechanical properties of polypropylene/multiwalled carbon nanotube (PP/MWCNTs)
nanocomposites. Samples were prepared via melt compounding method using a Haake
internal mixer at rotor speed of 80 r/min. The torque values in a 10-min compounding
period for the incorporation of MWCNTs fillers into PP matrix were analyzed and
thoroughly evaluated. The data was further confirmed by morphological analysis via
transmission electron microscopy. The efficiency of direct melt-compounding method
using internal mixer was evident from the 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 pretreatment 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. |
