In this work, nanocomposites with simultaneous dispersion of multiwalled carbon nanotubes (MWCNT) and montmorillonite clays in a high density polyethylene matrix were prepared by two different processes of preparation: solution and melt intercalation. The simultaneous dispersion of clays with carbon nanotubes (CNT) in different polymeric matrices has been showing a synergic potential for increasing mechanical properties, electrical conductivity and reducing the percolation threshold of the conductive phase. Two different montmorillonite clays were used separately: a natural (MMT-Na) and an organoclay (MMT-30B). The crystallinity degree and melting temperatures were evaluated by D.S.C., mechanical properties were evaluated by nanoindentetion. It can be seen that the process of preparation modify the degree of crystallinity of the HDPE matrix. Data from nanoidentention showed that the simultaneous addition of nanoclays and carbon nanotubes increased the Young's Modulus in both processes of preparation. |
