Construct graphene into porous three-dimensional structures
Kyoto, Japan -- Researchers in Japan have developed a novel yet simple technique, called "diffusion driven layer-by-layer assembly," to construct graphene into porous three-dimensional (3D) structures for applications in devices such as batteries and supercapacitors. Their study was recently published in the journal Nature Communications.
The resulting products display a foam-like porous structure, ideal for maximizing the benefits of graphene, with the porosity tunable from ultra-light to highly dense through simple changes in experimental conditions. Furthermore, the process is easily scalable for creating large-area films which will be highly useful as electrodes and membranes for energy generation or storage.
"While we have only demonstrated the construction of graphene-based structures in this study, we strongly believe that the new technique will be able to serve as a general method for the assembly of a much wider range of nanomaterials," concluded Franklin Kim, the principal investigator of the study.
