Absolutely. And bridges and roads. Graphene will mean the end of potholes, one way or the other.
But that’s only scratching the surface.
The electronic and optical potential of graphene is at least as exciting as are it’s mechanical and structural properties.
Water purification.
the holy grail of water purification is graphene membranes good enough for water desalination.
they have been able to produce it in the lab but not on an industrial scale
