Graphene nanoribbon

Graphene nanoribbons (GNR) are narrow strips of graphene with abundant edges and high aspect ratio. The edge functionalization can alter the chemical properties of the GNR to afford them good dispersibility and strong interfacial interactions with various materials. Such properties have made GNR suitable for producing a variety of composites, particularly as conductive fillers that provide percolation at a comparatively small mass loading due to the high aspect ratio and high conductivity. GNR have been used in sensors, energyconversion/storage devices, and electrochemical, photochemical and thermoelectrical systems. They have also been intensively studied for biochemical and biological applications such as bioimaging, biosensing, DNA sequencing, and neurophysiological recovery.

Graphene nanoribbons (GNR) made by reductive splitting of carbon nanotubes possess highly reactive edge carbon atoms. The carbanions have been passivated by methanol to yield this H-terminated graphene nanoribbons product. This reductively splitted graphene nanoribbons preserve high electrical conductivity, and enable them good candidates for electrodes in neurophysiological recording, conductive filler in batteries, and heater in de-icing devices.
