中文摘要：
利用具有优异导热性能的石墨烯制备了石墨烯／硅油热界面复合材料，研究了材料的相关性能，并将其用于高亮度LED路灯上的散热封装，在对其封装散热效果分析时发现，该热界面材料能有效地降低器件界面热阻，改善高亮度LED的散热问题；同时采用有限元模拟软件ANSYS对热界面材料的散热效果进行模拟，为改进LED封装技术提供了依据。
英文摘要：
The graphene （GN）/thermal interface material （TIM） with silicone oil （SI） were made by graphene which has good thermal conductivity. Researched the material＇s properties, and used it in the thermal package of HB-LED lights, to study the thermal package effect of TIM, it was found that the TIM could reduce the interfacial thermal resistance of the device effectively, and improved the HB-LED＇s heat problem; and simulated HB-LED heat distribution by ANSYS software, which provided the basis for the improvement of LED packaging technology.
