英文摘要： The effective control of thermal contact resistance (TCR) on heat management is the fundamental problem of performance and reliability in high power electronic devices. The main targets of this project are to focus on the TCR, carry out research such as the heat transfer character and the control method of the solid-solid TCR by using the new type thermal interface material (TIM) with graphene. With a focus on this urgent need of thermal management, this project will prepare with significant thermal transfer enhancement in modified graphene hybrid composites TIM. The study on TCR by using the TIM mixed with graphene for solid-solid materials will be deeply conducted. The quantitative study about doping of graphene, nano-metal particles and their hybrid composites into epoxy resins to minimize the total TCR will be conducted. The research on the new type TIM not only to the thermal conductivity of the TIM, but also to other factors such as the property of the filler, the microstructural characterization, and the surface morphology of the TIM. The influence on the TCR by the microstructural characterization and the surface morphology of the TIM will be revealed in deeply. The influence of the physical property of the TIM, interfacial structure, assembly pressure and surface morphology on TCR by using the TIM mixed with graphene for solid-solid materials will be discussed. The control method of solid-solid TCR by using the new type TIM will also be established. The research work will support the development of the enhanced method of TCR. This project solves the key problem, such as the heat transfer character and the control method of TCR by using the TIM mixed with graphene for the high-power electronic cooling. The research findings can enrich the connotation of thermal management, provide key technical support for the development of high-power electronic devices, improve the development level and satisfy the urgent needs of high-power electronic devices. Therefore, the research work of this project which focuses on the heat transfer characters of the new type TIM between solid-solid contact materials has merits both in a wide of academic significance and application value.
