Abstract
The results show that, under shear flow, the EVA/MWCNT composites exhibit some of the key rheological behaviors. At low shear rates (lower than 100 sâ1), the EVA/MWCNT composite behaves as Newtonian fluid for loading up to 0.5 wt.%, while at higher loading, the non-Newtonian behavior is more prominent. At shear rates higher than 100 sâ1, all composites exhibit shear thinning behavior (n < 0.4), indicating that the EVA/MWCNT composites are viable for the injection molding process. The dependence of shear viscosity on temperature is consistent with the Arrhenius equation and, for the investigated temperatures and shear rates, the viscosity increases linearly with increasing MWCNTs wt.%.
