As a single layer of graphite, graphene has been widely explored for its potential applications in many fields, such as electronics, energy storage, sensors, actuators, and composite materials. To achieve these purposes, assembling graphene nanosheets into macroscale bulk is indispensable. However, the prepared graphene materials at macroscale generally demonstrated a much lower performance in comparison to individual graphene nanosheets. Recently, great interest has been focused on the fabrication of graphene nanoarchitectonics, for the excellent properties of graphene at microscale are approaching at macroscale. During the fabrication process, four forms of driving forces are involved, including Van der Waals force, hydrogen bonds, ionic bonds as well as covalent bonds. In this feature article, we review the recent progress in 3D graphene architectures. This review highlights in materials' properties rather than the morphology and processing methodology, as understanding the relationship between the assembly driving force and the performance of bulk materials. This review would be beneficial to the design of new graphene nanoarchitectonics and achieve graphene-based materials with high performance. © 2014 Springer Science+Business Media New York. Source

As one of the most industrially important metals, copper (Cu) was successfully reinforced with graphite nanosheets (GNSs). A nacre-inspired laminated GNSs/Cu composite material was fabricated by a combination of ball-milling and hot-rolling techniques. During the ball-milling process, the GNSs were in situ produced from graphite exfoliation. The Cu-GNSs composite ingot was hot-rolled into a belt to form a laminated structure. The laminated Cu-GNSs composite material showed improved mechanical properties observed from tensile and three-point bending tests. The Young's modulus of Cu-GNSs composites was up to 170 GPa and the bending strength reached 660 MPa. This processing route was also advantageous in low-cost, mass-producing manufacture. © The Royal Society of Chemistry 2015. Source
