Abstract: As technology advances, the need for inexpensive polymer-based composites possessing high thermal conductive properties has become more and more important. Previously, the addition of thermal conductive particles, such as alumina, boron nitride and alumina nitride, has caused an increase in the thermal conductivity of the composite. Although an increase in thermal conductivity is present, an increase in fabrication costs is also experienced as a higher quantity of particles is required, in order to achieve the higher thermal conductivity readings. For this experiment, researchers set out to test the thermal conductivity of composites containing functionalized graphene nanosheets (GNSs), using the transient plane source method. As a result of the rigorous thermal conductivity testing performed, a non-destructive approach at increasing the thermal conductivity of GNS-filled epoxy composites was identified.
