Preparing three-dimensional graphene architectures：Review of recent developments

The recent development of synthesis processes to assemble graphene sheets into porous three-dimensional (3D) macroscopic structures are reviewed, including our efforts on 3D graphene structures. Mechanisms for building 3D graphene architectures and their composite materials are also summarized. The functional systems based on 3D graphene architectures provide a significant enhancement in the efficacy due to their unique structures and properties.
