Abstract:
      Single wall carbon nanotube（SWCNT）/butyl rubber（IIR） composites were prepared by melt and solution mixing processes，respectively，and the effects of the mixing process on the properties of the composites were studied. The results showed that，the electrical conductivity and dielectric constant of the composite could be significantly improved by the two-stage melt mixing process. Compared with the melt mixing process，the solution mixing process could not only improve the physical properties and heat resistance，but also significantly improve the electrical conductivity and dielectric constant of the composite.When the amount of SWCNT was 2 g，the electrical conductivity and dielectric constant of the composite were improved by using solution mixing combined with ethanol precipitation process.
