| 中文摘要: |
| 研究石墨/炭黑/EPDM复合材料的物理性能、动态力学性能和导电性能。结果表明：石墨对炭黑填充EPDM复合材料具有补强作用，并显著提高其导电性能；石墨/炭黑/EPDM复合材料的电导率-压力曲线表现出“山峰”形变化趋势，升高温度或增大石墨用量时该峰向低压力区移动；石墨用量越大，复合材料电导率的温度依赖性越强，石墨粒子滑移引起的转变温度越低。 |
| 英文摘要: |
| The physical properties,dynamic properties and conductive properties of graphite/carbon black/EPDM composites were investigated.The results showed that graphite could increase the strength and conductivity of carbon black filled EPDM composites.The conductivity-pressure curves of composites exhibited “mountain peak”,and peak position moved to lower pressure region as the temperature or graphite content increased.With more graphite,the temperature dependence of conductivity was stronger,and the transition temperature of the graphite-slip was lower. |
