| Abstract: |
| 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. |
