Graphene has excellent electrical conductivity, mechanical properties, and heat transfer properties. It is expected that the heat transfer efficiency will be improved by fabricating the nanofluid. However, graphene is prone to sedimentation because of its cohesion due to van der Waals’ binding forcein this study, we fabricated a nanofluid with enhanced dispersibility by surfactant and ball milling process. The dispersibility, zeta potential, absorbance and thermal conductivity of the nanofluid was measurede.
