Graphene spray and ...

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.

Graphene is basically 2-dimensional graphite. Graphite is soft and slippery because it’s in layers of 2-dimensional carbon atom "sheets" weakly bonded to other sheets of similar carbon.

Graphene is therefore a single "sheet" of carbon atoms arranged in hexagons. The carbon-carbon bonds in the 2-D section of graphite (and thus also graphene) are stronger bonds than carbon atom bonds in diamond, hence the "super" properties of graphene.

Graphene is right now rather difficult to make - it was literally discovered by putting a piece of scotch tape on graphite, carefully pullling up the tape leaving a single layer of graphene.

"Graphene is right now rather difficult to make - it was literally discovered by putting a piece of scotch tape on graphite, carefully pullling up the tape leaving a single layer of graphene."

Huh? Rather difficult? Sounds pretty easy to me. If it was difficult it wouldn't have been discovered accidentally. Tons of DIY videos on YouTube for the avid tweaker.

Thanks joeylawn butthat link didn't offer me any idea to explain the statement I read - that Magico 'was putting a layer of graphene' on the driver. Perhaps the comment was in error, a misunderstanding; and Magico is simply adding graphene particles or flakes to the slurry they use fabricating the driver material. That's the common usage.
