Rapid and Versatile Photonic Annealing of Graphene Inks for Flexible Printed Electronics

Data corresponds to the demonstration of photonic annealing to cure inkjet-printed graphene patterns. Few-layer graphene flakes are produced by liquid-phase exfoliation and stabilized by ethyl cellulose to formulate inks suitable for inkjet printing. Photonic annealing is applied as an alternative to thermal annealing for rapid processing and integration on temperature-sensitive substrates. Characterization of the materials using atomic force microscopy, Raman spectroscopy, thermal gravimetric analysis, and electrical measurements reveals suitable properties for application in printed and flexible electronics.
