The graphite in the form of malleable mass could be more economical to store and transport and less prone to combustion.
A team from the Northwestern McCormick Engineering School did the mass by adding an ultra-high concentration of graphene oxide to water.
The GO mass can be diluted to obtain gels or dry to produce hard solids. It can also be kneaded and re-formed, keeping an extreme deformation without fracture.
Jiaxing Huang, the study leader, said: "My dream is to convert graphene-based leaves into a widely accessible and easy-to-use engineering material, such as plastic, glass, I hope the GO mass can inspire new uses of graphene-based materials, just like the way in which gaming can inspire the imagination and creativity of young children. "
The mass can be formed in dense solids that are electrically conductive and chemically stable. It can also be further processed to produce graphene bulk oxides and graphene materials with tunable microstructures.
It is also ideal for manufacturing and massive loading. Currently, during transportation, GO stores them as solid or dry powder, or they become dilute dispersions, which multiply the mass of the material by hundreds or thousands.
Huang said that his final shipment of graphene oxide dispersed in 500 liters of liquid and had to be delivered by truck.
"The same quantity of graphene oxide in the form of mass weighs about 10 kilograms, and I myself could bring it," Huang said.
Although the addition of joints such as plastics would also turn GO into a state of mass, these additives would alter the properties of the material, unlike the addition of water.
