Like the ubiquitous carbon nanotube, graphene is another wonder substance composed entirely of carbon molecules. In fact, you can think of carbon nanotubes as sheets of graphene rolled into a tube. Graphite is also made from sheets of graphene stacked atop one another.

There are a few things about graphene that make it a fairly desirable material. First is its ability to conduct electricity and it does so quite well. Research into this property of graphene has made the future of flexible electronics quite tantalizing.

Second is its strength as compared to other substances on a molecular level. Graphene is 200 times stronger than steel, and the strongest of any material tested at present. This property also makes it ideal for flexible applications as the circuits constructed of graphene are much less likely to break under distortion.
