Abstract: In this study, the effects of the content of carbon black (CB) nanoparticle on the morphology of the emulsion polymer blends were investigated. The immiscible polymer blend was prepared with polystyrene (PS) and polypropylene (PP) in the absence and presence of different contents of CB nanoparticle in a twin screw mini extruder. The blend morphology was determined by Scanning Electron Microscopy (SEM) and the thermorheological properties by Differential Scanning Calorimetry (DSC) and Rheometric Dynamic Analyser (RDAII). The morphological results of blends prepared with and without CB nanoparticle showed a dispersion of circular particle in the matrix. The addition of CB nanoparticle decreases significantly the droplet size of the dispersed phase and also decreases the crystallisation temperature. The melt and transition temperatures remain less constant. The rheological properties of the blends are in between those of the two components for weak content of CB. However, when this content exceeds a critical value, the rheological properties increase significantly and exceed the properties of the two components. It was shown that a content of 4 wt% of CB nanoparticles was sufficient to achieve the percolation threshold in nanocomposite.
