▎ 摘 要
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 sp(2) network, via microcontact printing-induced multiple pi-pi stacking interactions. The GO/graphene hybrids, thus, provide a robust platform for chemical/photo-active GO for further chemical modification with multifunctionality.
