| 中文摘要: |
| 研究碳纳米管（CNTs）/白炭黑/炭黑补强溶聚丁苯橡胶（SSBR）纳米复合材料的导电性能。结果表明，当白炭黑用量小于50份时，白炭黑的阻隔效应占主导，CNTs/白炭黑补强SSBR纳米复合材料的导电性能较差；当白炭黑用量达到70份时，白炭黑的体积排除效应占主导，复合材料的导电性能较好。炭黑和CNTs的协同作用可提高CNTs/白炭黑/炭黑补强SSBR纳米复合材料的导电性能。偶联剂Si747改性复合材料的导电性能优于未添加偶联剂Si747的复合材料。 |
| 英文摘要: |
| 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. |
