Graphene-based materials have excellent conductivity, flexibility and chemical stability, revealing a promising prospect in printed electrics. This paper reviews the macro scale preparation of graphene-based materials, and introduces the technical characteristics and requirements of inks for inkjet printing, screen printing and 3D printing. The applications of graphene in printed electronic functional devices are summarized, mainly including transparent conductive films, flexible circuits, microsupercapacitors and wearable sensors. Existing problems and challenges in the current research are discussed. For the future development, it is envisioned that multi-functional, high performance device applications will be achieved through increasing structural diversity of printed circuits and focusing on the assembly strategy to enhance ordered arrangement of graphene building blocks.
