Abstract
Heat capacity of stacked-cup multiwalled carbon nanotubes (CNT) was measured in an adiabatic calorimeter over the temperature range (5 to 370) K. Results are compared with literature data on various samples of CNT and other carbon allotropes. The relatively large scatter of the heat-capacity data for CNT is discussed. The energy of combustion for multiwalled CNT (MCNT) was determined by combustion calorimetry and the enthalpy of formation was found from to be fHm = (0.6 0.9) kJ∙mol1. It is demonstrated that the thermodynamic properties of MCNT at T > 200 K are close to those of graphite. Equilibria of the MCNT synthesis were considered.Citation
