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

Abstract

In this paper, a continuum model is presented to investigate the thermal properties of carbon nanotubes<br><br>(CNTs). The proposed model considers each carbon–carbon (C–C) bond in CNT as a continuum solid element.<br><br>The thermal properties of the CNTs can be calculated simply by computing the thermal properties<br><br>of these solid elements. Considering a thermal resistance for each continuum solid element (C–C bond),<br><br>equivalent thermal resistance of CNTs can be obtained which is used to determine the thermal conductivity<br><br>of CNT. In order to find the thermal properties of C–C bond, Debye model has been utilized to calculate<br><br>the specific heat capacity and thermal conductivity. Then, extended calculations have been carried<br><br>out to study the thermal conductivity of armchair nanotube (10,10) and its variations with temperature.
