Extrusion reprocessing can significantly influence the structure and properties of polymer nanocomposites. In this study, two batches of polypropylene (pp) containing 4wt% of multi-walled carbon nanotube (MCNT) loading with 4wt% of two different types of compatibilisers were prepared (one in the presence of compatibiliser at low graft level and another one with compatibiliser at high graft level). The nanocomposites were passed into the extruder for three cycles and the resultant dispersion of carbon nanotubes, mechanical, rheological, and electrical properties of the nanocomposite after each cycle were examined. For both nanocomposites repetition of extrusion cycle improved tensile modulus, tensile strength and flexural modulus of the nanocomposites. Rheological and electrical characterisation indicated that the repetition of extrusion cycle enhanced the dispersion of nanotubes and helped the formation of percolation network. The electrical resistivity of the nanocomposites extruded three times was found to be up to nine orders lower than that of the first extrusion. From the morphological analyses performed by scanning electron microscopy it was observed that the multiple extrusions assisted homogeneous dispersion of carbon nanotubes within the polymer.
