| Abstract: |
| The conductivity of carbon nanotubes/silica/carbon black reinforced SSBR nanocomposites was investigated.The results showed that，when the addition level of silica was less than 50 phr，the barrier effect of silica was dominant，the CNTs/silica reinforced SSBR nanocomposites showed poor conductivity.When the addition level of silica was 70 phr，the volume exclusion effect of silica was dominant，the nanocomposites showed good conductivity.The synergistic effect between carbon black and carbon nanotubes could improve the conductivity of carbon nanotubes/silica/carbon black reinforced SSBR nanocomposites.The conductivity of coupling agent Si747 modified nanocomposites was better than that of the nanocomposites without coupling agent Si747. |
