Graphene spray and ...

an incorrect answer as sputtering is for conducting materials, like metals

Huh? Graphene is one of the most conductive materials in the universe. Which is why it's used to shield the SR Black fuse from RF and to improve conductivity in Graphene cables. Hel-loo!

Kind of OT, but does anyone know the name of a new material with similar properties to Graphene?

I was reading about it a few months ago, but lost the links.

there are dozens

try a search for "2D heterostructures" and see what pops up

Deekay, this may help " Beyond the study of graphene in the past decade, the discovery of other two-dimensional (2D) materials, like hexagonal-Boron Nitride (h-BN) and Molybdenum Disulfide (MoS2), have opened new doors in materials science and condensed matter physics." From OIST.

 Graphene is the basic structural element of common carbon based materials, including graphite, charcoal, carbon nanotubes and fullerenes(other molecules of carbon).
It is so strong because the electrical attraction between carbon atoms is very strong and that is the source of strength for both graphene and diamond.
