Graphene has a long list of superpowers. As a single layer of carbon atoms, it’s extremely lightweight and flexible. It’s also the strongest material on Earth. In fact, it’s about 200 times as strong as an equally thin sheet of steel. Electricity flows through graphene easily, and the material holds up even at high heat.

Such properties make graphene promising for a wide range of uses. It could help purify water or shield against mosquito bites. Or create faster, flexible electronics. Or increase the strength of plastic or cement. The list goes on and on. The huge potential of this material won its discoverers a Nobel Prize in 2010.

Unfortunately, graphene is still very difficult and costly to make in large amounts. That’s limited its widespread use. But scientists are trying to devise new, better ways to make this supermaterial. That includes ways to make it using waste carbon — which could help keep climate-warming carbon out of the atmosphere.

Graphene, for all its promising potential, is still largely a material of the future — here’s why.
