Graphene, being only one carbon thick and chemically stable, is not only the thinnest known material but, at 200 times the strength of steel, also the strongest. It can be stretched by 20 percent, but is also very stiff under compression with a Young modulus of about 1.0 TPa, which is comparable to diamond, Graphene is so robust and flexible that it can be folded; offering interesting possibilities for touch screens, bendable applications, and compact devices- picture a folded or scrolled piece of fabric containing integrated circuits. Graphene is also impermeable to gases including helium. It is twice as thermally conductive than copper. In addition, the thermal conductivity of graphene might be improved by changing its isotopic composition similar to the way it is in diamond- a diamond crystal that is 99.999 percent Carbon is 200 times more thermally conductive than naturally occurring diamond.
Most importantly, graphene is unlike any other material electronically.
