Graphene is going to be big in the future, I'll predict.
In aviation, transportation, and perhaps building and consumer electronics.
The 10 strangest facts about graphene | ZDNet
"4, 5 & 6. Best at electricity
And in case that doesn't impress you, Manchester University's Dr Leonid Ponomarenko points out that graphene also has "the highest current density (a million times that of copper) at room temperature; the highest intrinsic mobility (100 times more than in silicon); and conducts electricity in the limit of no electrons". Which means it can carry more electricity more efficiency, faster and with more precision than any other material.
8 & 9. Elastic
Well, for a crystal, anyway. Graphene stretches up to 20 percent of its length. And yet it is also the stiffest known material — even stiffer than diamond.
10. Thermal conductivity
Graphene also beats diamond in thermal conductivity. In fact, graphene now holds the record for conducting heat — it's better than any other known material."
