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

Adv Mater. 2015 Nov;27(42):6683-8. doi: 10.1002/adma.201502866. Epub 2015 Sep 30.

Abstract

Intense pulsed light (IPL) annealing of graphene inks is demonstrated for rapid post-processing of inkjet-printed patterns on various substrates. A conductivity of ≈25,000 S m(-1) is achieved following a single printing pass using a concentrated ink containing 20 mg mL(-1) graphene, establishing this strategy as a practical and effective approach for the versatile and high-performance integration of graphene in printed and flexible electronics.

Keywords: carbon nanomaterials; conductive inks; inkjet printing; intense pulsed light annealing; roll-to-roll processing.
