Graphene

Hi, A question for you who are in the know. Do we not utilize graphene in more beneficial ways because of its own strength? I heard graphene briefly discussed on a pod cast and they described the great uses and applications that it has, but that it really hasn't been used to it's full potential. Thanks in advance for your response.

Graphene is an interesting material, and has its' uses.

Be aware that it is not so easy to create in amounts, that woudl allow wide-spread use. A lot of universities and companies are reaesraching there.

Plus there is some suspicion, that graphene could exhibit toxicity, that is not well understood. Research here is also ongoing and not trivial.

Thank you, it seems that it could be very useful and beneficial for may fields.

@boonon
The problem for now not including toxicity is the way they get the stuff now is to peel off a layer one at a time and that is not conducive to industrial levels of production.

@sonhouse
Thank you. From what I have read That is the difficult part, peeling the stuff apart.

@boonon
Not only that but the amount they would take would be MAYBE 1 cm X 1 cm if that. Not exactly ready for prime time🙂

@boonon
It can be used for a digital brain interface.

Here is the downside.

@Metal-Brain
If it was known to be helpful medically, that problem would be overcome by chemical engineering, like the edges of the graphene getting molecules attached to limit that razor effect.

That would be actally chemistry, the chemical enginneering ios to bulit a process to do it in a bigger scale 😉

You don't even know if that is possible, let alone economically viable.

@Metal-Brain
You are talking to a working chemist so don't act like an idiot.

Aren't you retired? And why should I believe you? You said you used to work for NASA. What else do you claim to be? Are you an astrophysicist too? A lawyer? A beekeeper? What else?

@sonhouse
So right now we don't have a way to produce, extract it ,
A- economically
B- easily ? wrong word
C- what else?
Are the benefits of all the possible uses of graphene not beneficial enough to really explore how to produce it?

thanks

Of course there are several groups working hard on making appreciable ammounts in well characterized quality. And it is not as easy as it sounds (just put a pencil on the surface and draw ahead).

Perhaps the manufacture of graphene would be better facilitated by a zero-gravity environment...?

I guess trying to cleave a one-atom-thick sheet of graphene off a block of the stuff, even with some kind of extremely precise laser, is just too tricky.
