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?

...not wanting to potentially toss an 'accelerant' onto embers, But...

A cohort and I got excited (briefly) over 'graphene' as a speaker cone, until certain practicalities prevailed:
-cost
-source
-How does one handle an object 1 molecule thick?! *L*

2 mil Al or Ti is problematic enough...sure, it's supposed to be 'all the Good Stuff, But....adhesives, forming, and WTH would it look like?

My 'jury' still out....to lunch, to the pool, anywhere else for the time being.  I'm interested, but when a company that's selling a 3D carbon fiber printer can't form anything thin enough for a prototype....

Like class D amps.....there's going to be a period of growth before we can admire 'Practical Magic'.

Just saying...;)....MHO....I'll go away now...
How does one handle a material that’s one atom thick? One doesn’t handle it. The Graphene cones are a Graphene composite. Mystery solved!

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.
