| 中文摘要: |
| 采用超高速剪切分散的方法制备碳纳米管（CNTs）/硅橡胶纳米复合材料。试验结果表明，CNTs在复合材料中分散效果尚可；添加CNTs后，硅橡胶体积电阻率下降明显；与羟基化多壁CNTs相比，未羟基化多壁CNTs渗流阈值较小，对硅橡胶导电性能的提高作用较明显。 |
| 英文摘要: |
| Carbon nanotubes（CNTs）/silicone rubber nanocomposites were prepared by high speed shearing dispersion method.The test results showed that the dispersion of CNTs in composite was fair；the volume resistivity of silicone rubber reduced significantly as adding CNTs；the percolation threshold of non-hydroxylated multi-walled CNTs was lower compared with that of hydroxylated multi-walled CNTs and the electric conductivity of silicone rubber was significantly improved by adding non-hydroxylated multi-walled CNTs. |
