A thermal interface and a thermal interface as part of a thermal management system that comprises a heat source, and a cooling module. The heat source has an external surface; the thermal interface is a flexible graphite sheet article having two parallel planar surfaces, with the first planar surface of the thermal interface being in operative contact with the external surface of the heat source and the second planar surface being in contact with the cooling module. The graphite sheet contains oil.
