Role of Multiwalled Carbon Nanotubes (MWCNTs) on Rheological, Thermal and Electrical Properties of PC/ABS Blend

The main Objective of this work was to probe the effect of multiwall carbon nanotubes (MWCNTs) on Rheological, Thermal and Electrical Properties of Polycarbonate (PC)/acrylonitrile butadiene styrene (ABS) blend. Rheological properties showed that the MWCNTs mostly partitioned in the PC matrix. The microstructure of the nanocomposite samples is analyzed by scanning electron microscopy showing that the nanotubes are dispersed quite homogeneously in the polymer-matrix. The study of electrical properties of nanocomposite samples shows percolation threshold of the electrical conductivity at low filler loadings. Moreover, dynamic mechanical thermal analysis (DMA) was employed as complementary experiments
