Compounding extrusion of polypropylene carbon nanotube composites: Optimising and economizing process with a commercial perspective - A case study

Compounding extrusion of Polypropylene-Carbon nanotube composite is presented as a case study with Design of Experiments approach to identify best processing parameters for optimum dispersions and conductivity. Influence of Specific Mechanical Energy input on resulting morphology and volume resistivity of extruded strands are analyzed with statistical viewpoints. Resistances of the melt are measured with an online process monitoring approach and correlated with measurements on extruded strands. This aids process planning, and economization.
