Research status of graphene-based thermal interface material

With the continual increase demand in efficient heat dissipation for the electronic devices,graphene-based thermal interface materials has became a heated topic because of the excellent thermal properties in recent years. This paper provides a comprehensive review of the composition of graphene-based thermal interface material,the prediction model and test method of the thermal conductivity. And according to thermal conductivity model,the influencing factors of thermal conductivity were analysized,such as the intrinsic thermal conductivity of filler,filler volume fraction and its distribution in the matrix,the interface coupling strength. Finally,the future research and development were analyzed and prospected.
