Abstract
Graphene, as an outstanding representative of two-dimensional (2D) crystals, offers unique physics and exciting functionalities. Currently, the poor inter-sheet connections between isolated graphene flakes as building blocks break the continuous pathway for electron or phonon transports, and severely suppress the intrinsically high conductivity and mechanical strength of individual graphene flakes. The unavoidable re-stacking and agglomeration caused by Van der Waals forces-induced adhesion in standard graphene products diminishes the accessible surface area. Three-dimensional (3D) designed graphene architectures are thus most desired to bring all the extraordinary nanoscale properties of individual graphene flakes to macroscopic graphene assemblies for realizing practical applications. Here, I talk about a Sugar-Blowing approach based on a polymeric predecessor to synthesize a new 3D graphene bubble-network, i.e. strutted graphene. Strutted graphene consists of mono-/few-layered graphitic membranes tightly "glued", rigidly fixed and spatially scaffolded by micrometer-scale graphitic struts. Such topological configuration provides intimate structural interconnectivities, freeway for electron/phonon transports, huge accessible surface area, as well as robust mechanical properties. Strutted graphene opens up a wide horizon for diverse practical applications, e.g. high-power high-energy electrochemical capacitors.
