The　construction　of　a　three-dimensional　(3D)　conductive　network　is　a　potent　approach　to　achieving　high　electrical　and　thermal　conductivity　of　silicone　rubber　at　low　filler　content.　In　this　work,　silicone　rubber　composites　with　high　performance　were　prepared　by　constructing　a　2D-3D　collaborative　network　structure　in　a　matrix.　The　results　indicate　that　there　is　a　strong　interfacial　interaction　between　flake　graphites　(FGs),　conductive　sponges　(CSs),　and　silicone　rubber.　With　the　addition　of　FG　and　CS,　the　thermal　and　electrical　conductivities　of　silicone　rubber　composites　increase　of　0.51　W/m　center　dot　K　and　52　S/m,　which　were　320%　and　13　orders　of　magnitude　higher　than　that　of　pure　silicone　rubber,　respectively.　The　silicone　rubber　composites　also　display　good　thermal　stability　and　mechanical　properties.　Hence,　this　research　provides　a　new　paradigm　for　achieving　high-performance　silicone　rubber.
