| 中文摘要: |
| 研究单壁碳纳米管（SWCNTs）/丁基橡胶（IIR）复合材料（包括混炼胶和硫化胶）的性能。结果表明：随着SWCNTs用量的增大，SWCNTs/IIR混炼胶的t10和t90缩短，Payne效应增强，损耗因子增大，硫化胶的交联密度增大，耐热性能提高；SWCNTs对IIR具有补强作用，填充2份SWCNTs时补强效果最好；当SWCNTs用量为4份时，SWCNTs/IIR硫化胶的电导率、相对介电常数和介电损耗因子出现逾渗，当SWCNTs用量达到6份及以上时，硫化胶的导电性能趋于稳定。 |
| 英文摘要: |
| The properties of single wall carbon nanotubes（SWCNTs）/butyl rubber（IIR） composites （including the compound and vulcanizate） were studied.The results showed that，with the increase of SWCNTs amount，the t10 and t90 of SWCNTs/IIR compound decreased，Payne effect and loss factor increased，the crosslinking density and heat resistance of SWCNTs/IIR vulcanizate were improved.SWCNTs had a reinforcing effect on IIR，and the reinforcing effect was best when SWCNTs amount was 2 phr.The electrical conductivity，relative dielectric constant and dielectric loss factor of SWCNTs/IIR vulcanizate were percolated when SWCNTs amount was 4 phr，but when SWCNTs amount was 6 phr or more，the electrical properties of the vulcanizate tended to be stable. |
