                                主讲简介:Dr Yingyan Zhang obtained her Bachelor degree (2000) from Dalian University of Technology, China,her Master (2004) and Ph.D degrees (2008) from National University of Singapore (NUS). Later, she worked as a postdoc research fellow in Engineering Science Programme, NUS. In 2010, she joined University of Western Sydney, Australia as a faculty member.Dr. Yingyan Zhang's research interests include:1) Numerical methods in solid mechanics such as differential quadrature methods; 2) Atomistic investigation and continuum modelling of nanomaterials such as carbon nanotubes, graphene and graphynes  for their mechanical properties;3) Heat conduction of nanomaterials and their composites by molecular dynamics simulations. Till now, she has published 1 scholarly book, 4 book chapters and 73 refereed journal papers.  According to Google Scholar, her publications have been cited for 3697 times and her H-index is 31.

                                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.
