Now, Liangti Qu and colleagues report in Advanced Materials that the processability of graphene oxide is greatly improved when mixed with aniline, allowing the material to be moulded and printed into a diverse range of micro- and macroscale structures; from stars to elephants, many intricate structures are possible.

On mixing an aqueous solution of graphene oxide with aniline, graphene oxide balls of variable size precipitate out of solution. These balls have the consistency of a putty-like material and can be cut in half to reveal, using microscopic techniques, a tightly packed layer structure. X-ray diffraction shows a slightly larger interlayer distance than that in graphene oxide, probably as a result of aniline molecules embedded within interlayer regions.
