Graphene is a 2D material with a unique set of properties that make it extremely desirable in industry for a wide range of applications.

Despite the relatively short period of time since its discovery some applications have already seen some success. For example, its extreme mechanical and thermal properties make it perfect for composite materials and its transparency and high conductively have led to its use in touch screen technology. However, certain limitations have blocked its use in some industries, most notably in electronics where the lack of band gap and high contact resistances have meant that there has been little progress. Despite this, a great deal of research has focused on these problems because the rewards of using graphene are significant. As the material with the highest room temperature carrier mobility, it could be used to fabricate considerably faster field effect transistors (FETs) than traditional materials.
