we demonstrated the liquid crystallinity of graphene oxide aqueous dispersions. Despite the tremendous research interest in graphene oxide, its liquid crystallinity has first been demonstrated here. The liquid crystallinity could be maintained by including an additional polymer component in the solvent medium. This may significantly broaden the material composition and functionality of graphene oxide liquid crystals. Moreover, the orientation of graphene oxide liquid crystals could be manipulated by a magnetic field or mechanical deformation. Such versatility of graphene oxide liquid crystals along with their mass producibility from naturally abundant graphite offers a viable route to high-performance nanocomposites, optical materials, energy-storage materials, and many other applications. |
