Graphene,an atomic-thick layer of conjugated carbon atoms,is a typical two-dimensional (2D) polymer of pure carbon atoms.The physical and chemical characteristics of functional graphenes are closely related to the tailored structures of graphenes and their dimensionality,and therefore novel properties could potentially emerge from the dimensional confinement and/or benefit.In this regard,we have focused on development of new method and techniques for dimension-tailored fabrications of functional graphene architectures.
