چکیده

We demonstrate inkjet printing as a viable method for large-area fabrication of graphene devices. We produce a graphene-based ink by liquid phase exfoliation of graphite in N-methylpyrrolidone. We use it to print thin-film transistors, with mobilities up to ∼95 cm(2) V(-1) s(-1), as well as transparent and conductive patterns, with ∼80% transmittance and ∼30 kΩ/□ sheet resistance. This paves the way to all-printed, flexible, and transparent graphene devices on arbitrary substrates.

Direct printing of reduced graphene oxide on planar or highly curved surfaces with high resolutions using electrohydrodynamics.

Electrohydrodynamic inkjet printing of reduced graphene oxide (RGO) is de-monstrated to form complex geometric devices with high resolution (line width ≈ 5 mm). Both planar and highly curved surfaces (radius of curvature ≈ 60 mm) can be used as substrates. Demonstrations of counterfeit coin recognition using RGO patterns and all-printed RGO transistors suggest substantial promise for applicatio...

Graphene nanosheets as ink particles for inkjet printing on flexible board

Stable ink containing highly dispersed graphene nanosheets (GNSs) for inkjet printing on polyimide (PI) film has been successfully prepared by the adsorption of sodium n-dodecyl sulphate (SDS) and adjusting the pH value to 10 by ammonia. Conductive features on a flexible PI film were fabricated by inkjet printing the stable ink directly on a substrate. With higher number of printing cycles, the...
