| Popis: | This article describes the addition of multi-walled carbon nanotubes (MWCNT) into the epoxy as well as dispersing media during fabrication were used as factors to investigate the viscoelastic properties of epoxy/MWCNT nanocomposite. The quality of the dispersion was evaluated through studying the rheological and viscoelastic properties. The Perez model was then applied to analyze the viscoelastic behavior. Also, activation energy of the glass transition relaxation was calculated. Moreover, scanning electron microscopy was used to characterize the dispersion state of MWCNT. The results showed that the best rheological and viscoelastic properties were obtained for 1 wt.% MWCNT dispersed in epoxy in the presence of solvent. |
