Electric current induced reduction of graphene oxide and its application as gap electrodes in organic photoswitching devices.

This is owing to its exceptional physicochemical, electrical, mechanical, and biocompatible properties, which mean graphene-based materials have great prospects for applications in nanoscience and advanced materials. [ 1–3 ] Since the revival of the investigation of graphene in 2004, [ 4 ] various chemical and physical protocols have been developed to produce graphenebased materials. [ 1–8 ] Among these, chemical exfoliation of bulk graphite by intercalation using strong oxidizing acids has received much attention, since it can produce graphene-based materials on a large scale easily with low cost.
