Effect of Filler Morphology on the Electrical and Thermal Conductivity of PP/Carbon-Based Nanocomposites

In this paper, we studied the effect of different carbon-based nanostructures on electrical and mechanical properties polypropylene (PP) nanocomposites. Multi-walled carbon nanotubes (MWCNT), expanded graphite (EG), two black nanoparticles (CB) have been dispersed at several weight contents in polymer matrix through a melt extrusion process. The produced nanocomposites used to obtain samples for characterization by injection molding. dispersion has evaluated scanning electron microscopy (SEM) analysis. performed both DC AC configuration. with tensile test impact strength (Izod). thermal conductivity also evaluated. As result, MWCNTs are nanoadditive lowest percolation threshold. This allows MWCNT nanocomposite drastically change behavior without significant embrittlement observed other nanoadditives. However, CB surface area highest conductivity, even though high particle content. EG limited properties, but it is only one conductivity.
