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?

Omega eMats have Graphene in them? Interesting...

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 (spelling).

Just sayn: Beware or fraudulent and perposterous claims.....Jim

>>>>There are many ways to employ Graphene in things without having to deal with nanoscale material. As they have done with contact enhancer, tennis racquets, bicycle racing tires, bicycle frames, Graphene cables. You have to be able to use your, you know...🧠 Don’t be such a big baby.

By the way, Djokovic has been playing with Head Graphene tennis racquets for several years. Doesn’t seem to hurt his game. He’s ranked no. 2. Maybe it’s placebo effect. 😬

@fleschler "Okay, but I stand by whatever Tim Mrock uses in his Omega E-Mats, SR duplexes and SR fuses they all claim have graphene in them."

The word which destroys the valid argument is CLAIM. Where is the proof?

You cannot put 2D atomic level graphene into a liquid, and claim to have the same properties as a one level atomic sheet grafted onto a silicon base. It is not a trivial exercise to slice a one atom thick layer of Graphene which as a potential product is expensive and is still in the development stage of being applied to electronics. 

You can claim you have (the true atom thin) graphene, but proof is "proprietary" or "patent pending". Even as a fine talc powder in a solution, it is not true atom level Graphene.

@geoffkait  Yah. And spiders webs are stronger than steel too - and so what. If spiders webs could be produced in labs there’d be “tons” of marketing hype. And they would already be in use to “rigiditize” speaker cones. Yes, we need a new marketing word for any serious scam :). And Geoff - please identify just how many “tons” of graphene are being produced,where and by what company. The universities and research labs would love to know where to pick it up cheap. You could become useful to science! ;) (not)
