Creation of a Two-Dimensional Polymer and Graphene Heterostructure

Abstract

Van der Waals (vdW) heterostructures generated by stacking of graphene with other two-dimensional (2D) crystalline sheets have produced a new class of “designer” materials with a manifold of promises for nanoscience and nanotechnology. However, the 2D sheets are obtained either from nature or synthesized by high-energy procedures, which preclude the design of their structures as well as properties from molecular design on demand. Here, we introduced a rationally designed 2D polymer (one-monomer unit thick, freestanding network composed of periodically linked monomers) as a component to heterostructure construction, and created a 2D polymer-graphene heterostructure. The heterostructure has a high chemical stability, and could be thermally stable up to 400 oC. In the heterostructure, the 2D polymer doped graphene without changing its intrinsic structure, leading to enhancement of its electric conductivity by a factor of ∼ 2.5. This piece of work opens the door to tune the properties of graphene heterostructures with rational design for specific applications.
