Abstract: Polystyrene (PS)/graphite thermal conductive nano-composites were prepared to verify the high thermal conductivity values with the addition of graphite, as well as the layered structure. The thermal conductivity of PS improved greatly in the presence of the graphite. Researchers used the Maxwell-Eucken model and the Agari model to evaluate thermal conductivity. For the purpose of improving the interfacial compatibility of PS/graphite, three PS fabrication methods were introduced to determine any differences among morphologies, thermal conductivities and mechanical properties of the composite. By fabricating the composite via pan milling intercalation, it was determined that this method resulted in a much higher thermal conductivity value, than any other.
