#POLIMIrisponde – What are two-dimensional materials and what are they used for?

Two-dimensional materials, also called 2D materials, are materials extended along the surface, but of extremely reduced thickness, up to the atomic scale. We can think of sheets of paper, the thickness of which is reduced to a single or a few atoms.

Already in 1959, Richard Feynman, father of nanotechnology and Nobel Prize in physics, had questioned the uses of layered materials, by controlling the number of layers.

Since 2004, studies on graphene, the two-dimensional material par excellence, have shed light on these questions.

Carlo Spartaco Casari, professor of Materials Engineering and Nanotechnologies, talks about it.
