The influence of mechanical dispersion of MWCNT in epoxy matrix by calendering method: Batch method versus time controlled

The calendering approach has proved to be an effective alternative to chemical dispersion routes, but knowledge on the effectiveness of the different calendering parameters and methods used is still lacking. This study compared two different calendering methods widely used in the literature to evaluate possible differences in their dispersion effectiveness and their effect on the main properties of the nanocomposites being used. The nanocomposites' thermal, electrical, mechanical and thermomechanical properties were evaluated to exhaustively analyze the influence of each calendering method on these properties. Slight differences were observed in the dispersion effectiveness of the two methods analyzed, and behavioral differences were found in the nanocomposites with high and low nanoreinforcement contents.
