Direct supramolecular interacted graphene oxide assembly on graphene as an active and defect-free functional platform.

Graphene oxide (GO), which is structurally analogous to graphene, was used as the ink to precisely tune the surface activity of graphene, without diminishing the outstanding properties of the 2D sp2 network, via microcontact printing-induced multiple π-π stacking interactions. The GO/graphene hybrids, thus, provide a robust platform for chemical/photo-active GO for further chemical modification with multifunctionality.
