Research progress of thermally conductive graphene-based films

With the rapid development of contemporary technology, heat dissipation and heat conduction have become one of the key bottlenecks restricting the miniaturization of chip devices and the development of high-power manufacturing industry. The further application of traditional metal thermal conductive materials is limited by issues such as high density and easy oxidation. The non-metallic carbon-based materials represented by graphene-based materials have gradually become the focus of thermal conductive materials at home and abroad recently. This article reviews the methods and latest research results of preparing graphene thermal conductive films at home and abroad. This review article probes into the effects of heat treatment process, grain size, film density, impurity atoms and defects on the properties and physical mechanisms of graphene thermal conductive films. In addition, the development trends in this field are discussed
