Abstract A novel architecture of 3D graphene growth on porous Al 2 O 3 ceramics is proposed for thermal management using ambient pressure chemical vapor deposition. The formation mechanism attributed to the carbothermic reduction occurring at surface initialize nucleation and graphene. films are coated insulating anodic aluminum oxide (AAO) templates ceramic substrates. AAO possesses one‐dimensional isolated tubes, which can act as media directional transport. graphene/Al composite (G‐Al ) contains an interconnected macroporous framework with extremely low sheet electrical resistance down 0.11 Ω sq −1 conductivity 8.28 W m K . G‐Al provides enormous conductive pathways electronic heat transfer, suitable application sinks. Such a also attractive highly thermally reservoir hold phase change materials (stearic acid) energy storage. This work displays great potential CVD direct dielectric substrates conduction applications.
