Abstract: The addition of graphene nanoplatelets (GNP) to a paraffin-based solvent, eicosane was performed at various wt.% and subsequently the synthesized GNP/eicosane composites were analyzed by a variety of machines. The characterization of the GNP/eicosane composites was performed by the TPS technique for the measurement of thermal conductivity from 10°C to 35°C. At a wt.% of 10 GNP filler the composite had a thermal conductivity four times that of unfilled eicosane. Additional methods of analysis involved TEM, SEM and AFM among others. The amount of GNP filler didn't affect the melting point of the composite, although increasing amounts of GNP decreased the energy storage capacity of the composite slightly, which is acceptable in return for the increased thermal conductivity.
