Herein, we report a graphene foam (GF) with three-dimensional (3D) pore structure-based metal composites with excellent isotropic thermal conductivity and fast heat transfer performance. The 3D periodic structure of the GF？copper composites composed of high-quality multilayer graphene and copper was formed via a chemical vapor deposition (CVD) and a spark plasma sintering (SPS) process. The high-quality graphene layers in GF were well-bonded to copper, forming a clear interface without voids in the consolidated composites. Owing to the uniform 3D interconnection of graphene layer in the GF, in spite of less than 1 vol% carbon in the copper matrix, the GF？copper composites showed high isotropic thermal conductivity, which was higher by about 11 and 6% for in-plane and through-plane, respectively, than those of the bulk copper (∼400 W m？1 K？1). The superior performance of the 3D graphene-based metal？carbon composites offers remarkable opportunities in thermal management for advanced electronic and optoelectronic devices requiring high power density and efficiency. ？ 2021 English Elsevier Ltd Carbon carbon composites Chemical vapor deposition Copper Foams Heat transfer Metallic matrix composites Spark plasma sintering Thermal conductivity Van der Waals forces 3-dimensional 3D graphene Copper-composites Graphene foams Graphene layers Heat transport High quality Isotropics Metal-carbon composite Thermal Graphene Swift isotropic heat transport of 3D graphene platform-based metal-graphene composites Article 10.1016/j.carbon.2021.07.008 1 Carbon, v.183, pp.93 - 99 Carbon 183 93 99 scie scopus 000705083800009 2-s2.0-85109522362 Chemistry, Physical Materials Science, Multidisciplinary Chemistry Materials Science Article Carbon carbon composites Chemical vapor deposition Copper Foams Heat transfer Metallic matrix composites Spark plasma sintering Thermal conductivity Van der Waals forces 3-dimensional 3D graphene Copper-composites Graphene foams Graphene layers Heat transport High quality Isotropics Metal-carbon composite Thermal Graphene 3-Dimensional Graphene Heat transfer Isotropic Metal-carbon composites Thermal conductivity
