The nanocomposites were derived from melt mixing of carbon nanotubes (CNTs) in Polyamide 6 (PA6)/Polypropylene (PP) blends. Nanotubes tend to aggregate into ropes or bundles, which cause poor dispersion in the polymer matrix. using a modification method based on phosphonium salt functionalization of nanotubes could be effective. The investigations of morphological and rheological properties indicate that PA6/PP/MWNTs (3 wt.% MWNTs) nanocomposites have a specific segregated network when the addition of phosphonium based modifier performed via sonication together with MWNTs in ethanol. Characterizations exhibited that conducting network is produced in samples prepared by route 1. Consequently, electrical conductivity reached up to 8 orders of magnitude more than the sample of modified by route 2.
