| 中文摘要: |
| 考察了纳米导电纤维(Nano-F)/导电炭黑填充硅橡胶胶料的流变性能。结果表明，在低剪切速率下，Nano-F的各向异性增加了硅橡胶分子链缠结点，阻碍其在流场中的取向，提高了胶料的表观粘度；在高剪切速率下，Nano-F的取向有助于硅橡胶分子链的取向运动，可降低胶料的表观粘度，改善胶料的加工性能。 |
| 英文摘要: |
| The rheological properties of silicone rubber compound filled with conductive nano-fibre(Nano-F)/conductive carbon black were investigated.The results showed that the entanglement points in the molecular chains of silicone rubber increased by the anisotropy of Nano-F at low shearing rate，which hindered the orientation of rubber molecular chains and resulted in a higher apparent viscosity of compound；the orientation of Nano-F at high shearing rate was benificial to the orientation of silicone rubber molecular chains，which resulted in a lower apparent viscosity of compound and thus an improved processibility of compound. |
