Modeling issues regarding thermal conductivity of graphene-based nanocomposites

ABSTRACT: Modeling thermal conductivity of graphene-based nanocomposites is analyzed from an effective medium approximation point of view, where interfacial thermal resistance and arbitrary shape of the fillers are considered. Two approximations, Maxwell-Garnett and coherent potential approximation, are used to show that the usual oblate spheroidal shape approximation of graphene nanodots is not satisfactory to model thermal conductivity in graphene-based composites.

KEYWORDS: Composites, graphene, graphene-based composites, thermal conductivity, thermal interface materials, Maxwell-Garnett approximation, coherent potential approxima- tion
