Although hundreds of two-dimensional crystals exist, graphene is indisputably the most well-known. Why is it so famous? Certainly, due to its intrinsic characteristics. In fact, graphene is made of a layer of monatomic carbon, which has a mechanical resistance about 100 times higher than iron, thickness being equal, and moreover, it is flexible and stretchable. It has extraordinary thermal and electric conductivity, its current carrying capacity being higher than copper. In addition, it is optically transparent, has a huge surface area and is a virtually impermeable barrier against the vast majority of chemical elements.
Thanks to its intrinsic properties, its wide potential of application and the possible commercial impact, graphene has recently attracted great interest both in the scientific community and in the industrial sector. This is also reflected in the Graphene Flagship (currently the largest research program financed by the European Union, with a budget of about one billion Euro in 10 years, http://graphene-flagship.eu). In particular, in the organization chart of the Graphene Flagship, some of our founding partners play an essential role of development, innovation and coordination.
