Effect of processing technique on the transport and mechanical properties of graphite nanoplatelet/rubbery epoxy composites for thermal interface applications

► Graphite nanoplatelet (GNP)/rubbery epoxy composite as thermal interface material. ► Mechanical mixing (MM) and speed mixing used for composites fabrication. ► GNPs loadings in rubbery epoxy depend on particle size and distribution. ► Improved transport properties of composites produced by MM. ► GNP/rubbery epoxy composites are highly compliant compared to GNP/glassy epoxy composites.
