We demonstrate a straightforward selfassembly method to fabricate highly ordered, mechanically flexible macroporous RGO assemblies with tunable open porous morphologies. The self-assembly of chemically modified graphene oxide platelets into a complex three-dimensional morphology was achieved by the “breath-figure” method, which is a straightforward procedure for synthesizing large-area porous polymer films. The pore size and the number of porous layers were effectively controlled by the concentration of the organic precursor disperson and the length of polymer chains grafted to the GO surface. Additional N-doping of these 3D carbon assemblies enhanced their electrical conductivities and facilitated further chemical functionalization under mild aqueous-based processes. Our facile preparation of highly ordered macroporous graphene film may find utility in various applications, including energy storage/conversion, biological scaffold, supporting frameworks of catalyst, and sensors. |
