The outstanding thermal and mechanical properties of graphene offer the possibility of a new generation of thermal interface materials. Graphene provides a more efficient network for heat flow inside the polymer matrix because of their unique structure. However, although their unique properties, recent researches show that thermal conductivity of graphene/polymer composites is very low. In this study, graphene was modified with silane coupling agent to improve this problem. Thermal and electrical conductivity of epoxy/graphene modified with silanecoupling agent composites are higher than raw graphene incorporated epoxy composites. Fourier transform infrared spectroscopy (FT-IR, VERTEX 80 V, Bruker), Thermogravimetry analysis (TGA, SDTA 851) and Energy-dispersive X-ray spectroscopy (EDX, 6853-H, HORIBA) were used to confirm the incorporation of silane coupling agent on the surface of graphene. |
