In this study, the cure kinetics, rheological and electrical behaviors of the MWCNTs/epoxy nanocomposites produced using a three-roll mill are studied. After defining the domain of linear response, the influence of temperature and MWCNTs on the shear viscosity has been investigated. The shear-thinning effect caused by adding CNTs to the epoxy matrix is more pronounced at increased temperature and MWCNT weight content. Furthermore, a mechanical manifestation of the percolation phenomenon may have been observed. At last the electrical conductivity was investigated to characterize the percolation behavior and determine the best CNT content/electrical properties ratio.
