The thermal conductivity in Z direction is approximately 10 ~ 20 (w / mk). The graphite sheet keeps high-thermal conductivity by a covalent bonding of carbon crystal structure, firmly bonded in XY direction.
However, as anisotropic material, the thermal conductivity in Z direction bonded by intermolecular bonds differs from that of XY direction. In addition, the above mentioned thermal conductivity varies according to measurement condition, is not a guaranteed value.
