This work reports temperature-dependent thermal conductivity, specific heat and thermal diffusivity measurements of multi-wall carbon nanotube strands. Thermal property characterization has been carried out along the carbon nanotube alignment direction with an AC driven, self-heating 3ω method over a temperature range from 90-310K. The specific heat and thermal conductivity increases linearly with temperature. The thermal diffusivity is 5×10-6 m2s-1 at room temperature and is nearly constant across the temperature range, slightly increasing at lower temperatures. The observed trends in specific heat and thermal conductivity are similar with other published multi-wall carbon nanotube data. The measured thermal diffusivity agrees with data reported elsewhere for the same MWCNT material measured by a different technique.
