At present, the studies of 3D graphene-based polymer composites or 3D graphene/inorganic nano composites have made a substantial progress. Researchers have realized 3D well-aligned and controlled assembly between graphene and functional component via abundant physical and chemical route. With the unique structure and excellent performance, 3D graphene- based composites show great potential in energy storage, environmental protection, sensor, etc, This article reviews recent progress in preparation and application of 3D graphene-based composites, involving the 3D graphene/polymer composites system and the 3D graphene/inorganie nano composites system. 3D assembly methods of the two systems are summarized, and the structural features of the composites are analyzed. The application progress of 3D graphene-based composites is briefly introduced. Finally, the development prospect of 3D structure design and diverse applications in the future are also proposed.
