Graphene Nanomaterials is expected to fill a void in knowledge among practitioners generated by the discovery of graphene as a distinct allotrope of carbon (2010 Nobel Prize in Physics) with the potential to affect further increases in speed of microprocessors beyond 30 petahertz. It has other interesting performance properties. Identified in 2004, currently the number of patents in graphene is 7,351 and the number is rising rapidly. This book provides information on the synthesis, characterization, application development, scale-up, stability analysis using a pencil and paper, and structure-property relations. With less than 24,000 atoms/25 nm, the nanosheet form is metastable. Thirty-nine different nanostructuring methods were reviewed in an earlier book including epitaxy, lithography, deposition, exfoliation, etc. With the thickness of only a few atomic layers, graphene has superior field emitter properties, is 100 times stronger than steel, flexible as rubber, tougher than diamond, and is 13 times more conductive than copper. Electron mobility in graphene has been found to be 200,000 cm2V-1s-1.
