Beware of new material claims - the case of graphene


Given that graphene is quite the in vogue material for audio applications I wonder how many (if any) of the vendors selling this are actually sourcing the real thing?

I think I'll save my $$$ and stick with copper or silver and a good tight connection and pass on all the Graphene hype. As far as Graphene infused speaker diaphrams, well, I won't go there...Jim
Actually geoff, twas not guidocorona refering to Total Contact's claim of their product being a superconductor:

@fleschler  Total Contact uses graphene; however, it has a proprietary other product in it that allows it to be a super conductor per the manufacturer as well as a process which melds the two to work concurrently.

By very deffinition, Graphene is a micro thin layer (acording to guidocorona, a mono-atomic, layer) of carbon. That's what makes it Graphene and what allows it's extreme qualities. It can't be gooped up in a solution with something else and still be considered Graphene, or expected to posess the qualities of Graphine.
 Just sayn: Beware or fraudulent and perposterous claims.....Jim
China can’t seem to get dog food right, I don’t think I’d put much trust in their Graphene......Jim
@ geoffkait
That was an interesting and impressive video. Samsung is developing  the use of graphene to produce a rapid charge battery. Utilizing graphene as a micro coating on a chip or in a battery is expensive, extensive, processes but is showing great promise in the production of some incredible products.
Although labs are developing processes to curl mono-atomic (2D) graphene sheets, into micro 3D spheres and strands, also shows great promise, companies producing tons of stuff they claim to be graphene powder, to be used to add a bit of magic to everything from condoms to hair spray - leaves me more than a little skeptical.....Jim

WOW! You just gave them two wonderful, or not so wonderful, new  ideas for the use of Graphene:
A Powdered Graphene Supplement to mix with ones breakfast drink and Invisable Killer Thread.
I think you're on to something......Jim
