Research progress of thermal transprot of graphene-based composite thermal interface materials

With the rapid increase of the thermal power density of electronic equipment, controlling its temperature has become an urgent need for the development and application of the electronic industry. One of the core problems in the selection of thermal interface materials is the development of high-performance graphene-based composite thermal interface materials, which has become a hot research topic in science and industry. The core problem is to improve the effective thermal conductivity of graphene and the interfacial thermal conductance between graphene and matrix, which needexploring and reviewing in depth from the physical mechanism. In this paper, the recent research progress of the internal thermal conductance of graphene-based composite systems is summarized. The development trend of thermal transport regulation in graphene-based composite systems is also prospected, and the unsolved problems and bottlenecks appearingin thecurrent research are discussed. This study will be helpful in understanding the fundamental issues of thermal conduction in graphene-based composite systems, and provide useful guidance for the application of thermal management in the fields of electronics, optoelectronic devices, and batteries. © 2022 中国物理学会 Chinese Physical Society.
