Abstract

The advent of the 5G era has stimulated the rapid development of high power electronics with dense integration. Three-dimensional (3D) thermally conductive networks, possessing high thermal and electrical conductivities and many different structures, are regarded as key materials to improve the performance of electronic devices. We provide a critical overview of carbon-based 3D thermally conductive networks, emphasizing their preparation-structure-property relationships and their applications in different scenarios. A detailed discussion of the microscopic principles of thermal conductivity is provided, which is crucial for increasing it. This is followed by an in-depth account of the construction of 3D networks using different carbon materials, such as graphene, carbon foam, and carbon nanotubes. Techniques for the assembly of two-dimensional graphene into 3D networks and their effects on thermal conductivity are emphasized. Finally, the existing challenges and future prospects for 3D carbon-based thermally conductive networks are discussed.

期刊介绍： New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
