Graphene spray and ...


Graphene film is here and I feel potentially incredibly interesting for our hobby.
Magico is coating their 7.5 inch speaker with graphene. Does anyone know 
what method they use?

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

as someone correctly pointed out earlier Graphene is conductive. Can’t you read? It’s high conductivity is why it’s useful in the uh, Graphene cables and as RF shield in the SR Black fuse. Have you been nodding out on us again? Your continued stalking is duly noted.

If the signal is transmitted 200 times faster using Graphene that means the audio signal will be traveling approximately 150 times faster than the speed of light. Whoa!!

Maybe Samsung should use Graphene in their smart phone batteries.
Since the Graphene is used as a coating it can be applied as a thin light tape, which would be stable. You can buy Graphene tape all over the Internet, no big deal. Even better DIY.
Huh? No more difficult than, say, making titanium tweeters or applying a one molecule thick 24 carat Gold reflective layer on Gold CDs. 


"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.

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!


Maybe, just maybe, Magico copied the technique Synergistic Research uses to coat the Black fuse with Graphene.

Same way they get the transparently thin 24 carat gold layer on CDs. Sputtering. Final answer.

I defy anyone to spray on a precisely one molecule thickness of Graphene.

Can you write with it? But seriously Graphene is only one molecule thick by definition so however they apply it it must be done very carefully. Maybe with teeny tiny tweezers. Maybe the same way Head applies it to their tennis rackets.
