Development of the next generations of integrated circuits,three-dimensional integration and ultra-fast highpower density transistors makes the thermal management requirements became a critical issue.Efficient heat removal helps to improve for the performance and reliability of modern electronic,optoelectronic,photonic devices and systems.The thermal interface materials(TIMs),applied between heat sources and heat sinks,are essential ingredients of thermal management.Recently,graphite nanosheets(GNs)has attracted considerable attention of many researchers because of its excellent properties such as good electrical conductivity and high thermal conductivity.
