HighlightsA composite thermal interface material with three-dimensional hybrid carbon network-reinforced polydimethylsiloxane was proposed.The cooperative regulation of thermal conductivity and mechanical properties was achieved by controlling the assembly process of micro-nano scale unit carbon materials.The orthotropic continuous carbon structure endowed the composites with in-plane and out-of-plane thermal conductivities of up to 113.61 and 24.37 W m−1 K−1, respectively.The excellent compressibility and adhesion properties cooperatively improved the effective thermal conductivity by more than an order of magnitude.
