Thermal properties of graphite- thermal conductivity ...

The thermal properties of conductivity and expansion are strongly influenced by the anisotropy of the graphite crystal. The thermal conductivity (K) is the time rate of transfer of heat by conduction. In graphite, it occurs essentially by lattice vibration and is

2018-4-11  The thermal conductivity was increased from 0.93 W m −1 K −1 for neat polymer to 2.73 W m −1 K −1 after the addition of 30 wt% graphite, whereas after the inclusion of 1 wt% CNT, the thermal conductivity value reached 3.8 W m −1 K −1. This is ascribed to the additional CNT bridges which closely adjoin the surface of graphite.

2021-11-5  Even though a steeper enhancement in thermal conductivity happened, the thermal conductivity of the 5EG/10MLG/TPU composite only achieved 2.71 Wm −1 K −1, slightly higher than that (2.34 Wm −1 K −1) of the 15EG/TPU composite. This demonstrated a weak thermal synergy between a few EG fillers and the percolated MLG network.
