Abstract
1D carbon nanotubes (CNTs) and 2D graphene are representative sp 2 ‐hybridized carbon nanomaterials with excellent physic‐chemical properties and promising application potentials. The same hybridization configuration allows the graphene/CNT composites for orderly stacking and covalent bonding in nanoscale to construct all‐carbon architecture as an ideal material platform and synergize their fascinating attributes beyond each of them. However, deliberate control over fine structural and compositional attributes, as well as thoroughly understanding the structure‐performance relationships, remain challenging. To facilitate further advancements in 3D graphene/CNT composites, this review summarizes recent progress on their structures, properties, synthesis methods, and applications while also highlighting existing problems and critical challenges for future research.
