报告摘要:Fast growing power densities of modern electronic devices demand high-performance thermal interface materials (TIMs). Owing to a superior thermal conductivity of graphene, composites with graphene fillers dispersed in polymer matrix are expected to be promising TIM candidates. However, the thermal conductivity of graphene-polymer composites is hindered by a high thermal resistance across the interfaces between graphene fillers and polymer matrix.

The presentation will share our recent works about reducing the thermal transport across the graphene-polymer interfaces by employing a variety of treatment methods. Using molecular dynamics (MD) simulations, the effectiveness of covalent functionalisation, non-covalent functionalisation, dopants, defects and acetylenic linkages in reducing the graphene-polymer interfacial thermal resistance is investigated systematically. We found that the covalent and non-covalent functionalisation techniques could considerably reduce the graphene-polymer interfacial thermal resistance and they are a useful technique to enhance the thermal conductivity of the graphene-polymer composites.
