Inkjet Printing of High Conductivity, Flexible Graphene Patterns

Ethan B. Secor, Pradyumna L. Prabhumirashi, Kanan Puntambekar, Michael L. Geier & Mark C. Hersam
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...
