Inkjet Printing of High Conductivity, Flexible Graphene Patterns

The data corresponds to the demonstration of inkjet-printed graphene patterns using polymer ethyl cellulose as an effective ink stabilizer. Few-layer graphene flakes are produced by liquid-phase exfoliation and stabilized by ethyl cellulose to formulate inks suitable for inkjet printing. Printed patterns exhibit high conductivity and mechanical flexibility following a mild thermal annealing step. Characterization of the materials using atomic force microscopy, scanning electron microscopy, thermal gravimetric analysis, and electrical measurements reveals suitable properties for application in printed and flexible electronics.
