| 中文摘要: |
| 用导电炭黑EC-600JD和BP2000与石墨烯纳米片填充硅橡胶制备导电硅橡胶，并测试其电性能和力学性能。结果表明：填充导电炭黑BP2000的硅橡胶的电性能优于填充导电炭黑EC-600JD的硅橡胶；在硅橡胶中填充25份导电炭黑BP2000和一定量石墨烯纳米片，随着石墨烯纳米片用量的增大，导电硅橡胶的电性能逐渐提高，当石墨烯纳米片用量为1份时，导电硅橡胶的力学性能最优，电性能较好，达到电热平衡时间最短，压阻特性最不明显。 |
| 英文摘要: |
| The conductive silicone rubber was prepared by filling the conductive carbon black EC-600JD and BP2000 and graphene nanosheets，and its electrical and mechanical properties were tested. The results showed that the electrical properties of the silicone rubber filled with BP2000 were better than those of EC-
600JD filled silicone rubber. When 25 phr of BP2000 and a certain amount of graphene nanosheets were filled in the silicone rubber，with the increase of the amount of graphene nanosheets，the electrical properties of the conductive silicone rubber were gradually improved. When the amount of graphene nanosheets was 1 phr，the mechanical properties of the conductive silicone rubber were the best，the electric properties were better，the time to reach the electrothermal balance was the shortest，and the piezoresistive characteristic was the least obvious. |
