Polyethylene/carbon nanotubes, PE/NTC, nanocomposites were synthesized by in situ polymerization for comparison with polyethylene/graphene nanosheets, PE/NG, nanocomposites obtained in the same conditions. The nanocomposites of polyethylene/NTC were obtained with good catalytic activities and were characterized by DSC and TEM. The nanocomposites with NG showed better thermal stability than with NTC, however, no significant differences in dynamic mechanical properties were found. In the electrical conductivity study, PE/NTC nanocomposites reached conductivities of semiconductor materials at lower content of filler than PE/NG nanocomposites.
