A novel approach for determining thermal properties of single-walled carbon nanotubes

► A continuum model is developed for determining the thermal conductivity of CNT. ► The thermal conductivity of CNTs is a function of temperature and chirality. ► The thermal conductivity of CNT (10, 10) at 300 K is predicted as 9750 W/mK. ► The phonon mean free path and the thermal conductivity increase with chiral number.
