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。 |

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. |
