主讲内容：Owing to the superior thermal properties of graphene, graphene-reinforced polymer nanocomposites hold great potential as the thermal interface materials (TIMs) dissipating heat for electronic packages. However, this application is greatly hindered by the high thermal resistance at the interface between graphene and polymer. In this talk, I shall share with you our recent research work about the thermal transport properties of graphene-polymer nanocomposites. Some important aspects of the improvement of the thermal transport across the interface between graphene and polymer matrix in their nanocomposites, the effects of covalent and noncovalent functionalization, isotope doping, and acetylenic linkage in graphene are systematically investigated using molecular dynamics (MD) simulations.The simulation results show that the covalent and noncovalent functionalization techniques could considerably reduce the graphene-polymer interfacial thermal resistance in the nanocomposites.
