Improvement of thermal conductivities for silicone nanocomposite via incorporating poly(γ-methacryloxypropyltrimethoxy silane) grafted graphene fillers

摘要

Graphical abstractDisplay OmittedHighlights?Surfaces of RGO are grafted by poly(γ-methacryloxypropyltrimethoxy silane).?g-RGO/SI shows better thermal conductivity than RGO/SI.?Complex interface network structure benefits forming heat transport chains.?Interfacial thermal conductance enhances the extrinsic thermal conductivity.AbstractThe proposed grafting polymerization of γ-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(γ-methacryloxy
