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?

Spray gun comment is accurate as long as you have rocket fuel and an extremely high temperature oven. I'm still hoping someone knows the answer to my question. 
Deekay, I too would have been skeptical if there wasn't so much interesting
literature on this most recent use of the same carbon that's in common lead pencils.
Your ideas on application are not unreasonable but a little research will reveal the
unusual and difficult processes involved that I came across to create graphene. That's why I'm very interested in how Magico claims to have coated their driver with graphene.
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.
geoffkait, he meant to say - difficult to make-- so as to be practically useful. And it is.
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.
Very interesting davidpritchard. They have their fingers in so many pies. It's bound to be interesting. It appears that graphene is vastly more exciting than diamonds,kevlar,spectra,teflon--as it has qualities that seem to give the potential of it surpassing all commercial applications.
Mmeysarosh I followed up on your comments and found it very interesting
how the graphene helps tire performance in a number of ways. It could find interesting application in ultra high power dragsters where sidewall wrinkling wastes power. I think it will ultimately 
be useful in a number areas in audio,particularly in cones and domes,perhaps competing with diamond, and also maybe even in providing more precision in the rubber surrounds.and as an extreme performance surround material.
Looking into Samsung's research it appears they're on the cusp of making use of it for transistors. And as graphene transmits electrical signals 200 times faster than the currently used material it's not hard to see the potential. 
Thanks almarg.
If new graphene technology can make our 
preamp,amp and digital equipment 'faster' I think 'cleaner' signals will be the result; giving us better sound.
Mmeysaroch. Very interesting. I think distortion reduction and the extended
frequency response w/o breakup would be terrific benefits. Luckily there's so much research going on I think we'll get products fairly soon (not the current products that advertise graphene but are probably using plain old graphite ; as there's no explanation about their manufacturing processes-which have to be discussed to be believed).
Geoffkait, once we're talking faster than the speed of light-I think it's getting "verry interestink" per Sgt. Schultz
Non of these little companies can do research on graphene.
When it's available in a form they can use,they will.
