چکیده

The main objective of this work was to probe the effect of multiwalled carbon nanotubes (MWCNTs) on the rheological, electrical and thermal properties of polycarbonate (PC)/acrylonitrile butadiene styrene (ABS) 75/25 blend prepared by simultaneous melt blending. The results of thermodynamics measurements suggested that the MWCNTs were preferentially localized in the interface of the PC and ABS; however, melt linear viscoelastic measurements and TEM results showed a greater affinity of MWCNTs towards the PC matrix. This was also supported by the electrical percolation threshold observed at low MWCNTs content. The microstructure of the samples was analyzed by melt linear viscoelastic experiments and electron microscopy, which revealed that the MWCNTs were dispersed quite homogeneously in the PC matrix. The electrical conductivity and electromagnetic interference shielding efficiency (EMI SE) of the blend nanocomposite samples were enhanced with increasing the loading level of MWCNTs. Finally, thermal analysis was employed as a complementary experiment to provide further evidence for MWCNTs' partitioning.
