Photothermal Deoxygenation of Graphene Oxide for Patterning and Distributed Ignition Applications



original image

Photopatterning of graphene oxide films can be achieved by exposing a thin film of graphene oxide to a photographic flash. Absorption of light causes rapid heating of the graphene oxide resulting in deoxygenation to graphitic carbon. Using a transmission electron microscope grid as a mask, the grid pattern can be transferred to a graphene oxide film.
