The proposed grafting polymerization of gamma-methacryloxypropyltrimethoxy silane was performed to functionalize graphene, aiming to fabricate functionalized graphene/silicone with excellent thermal conductivities. The surface morphology and element content of poly(gamma-methacryloxypropyltrimethoxy silane) grafted reduced graphene oxide (g-RGO) was characterized by Atomic force microscope (AFM) and X-ray photoelectron spectroscopy (XPS). The usage of g-RGO was benefit for improving the thermal conductivity of silicone (SI). The g-RGO/SI (2 wt% filler) had thermal conductivity of 1.31 W.m (1).K (1) and thermal diffusivity of 1.08 mm(2).s (1) (increased by 620% compared to that of SI), which held potential for electronic packaging materials and micro-electro-mechanical systems apparatus.
