Description
  • The presented work is devoted to the investigation of the influence of single wall carbon nanotubes (SWCNT) on the thermal and mechanical properties of rubber blends. The materials under investigation were rubber blends filled by carbon black (CB-labelled as standard or S) or a mixture of CB with single wall carbon nanotubes (0.6 wt.% of SWCNT). The thermal parameters of the rubber samples were measured on the basis of an exponential model of a cooling body (developed in a lumped capacity model). From the measured cooling curve of the sample after its deformation, the specific heat capacity cp [J/kg/K], thermal diffusivity α [m2/s] and thermal conductivity k [W/m/K] were measured. The increase of α and k was observed for rubber blends filled with a mixture of CB and SWCNT. The complex thermo mechanical analyzer (CTMA) was used for determination of thermal and mechanical parameters. The static Young's modulus shows an immense increase after SWCNT addition. The dynamic Young's modulus also shows an increase after SWCNT introduction. A simultaneous tgδ decrease caused by SWCNT presence is observed in this case.
